The AD8129/AD8130 are designed as receivers for the transmission of high speed signals over twisted-pair cables to work with the AD8131 or AD8132 drivers. Either can be used for analog or digital video signals and for high speed data transmission. The AD8129/AD8130 are differential-to-single-ended amplifiers with extremely high CMRR at high frequency. Therefore, they canalso be effectively used as high speed instrumentation amps or for converting differential signals to single-ended signals.The AD8129 is a low noise, high gain (10 or greater) version intended for applications over very long cables, where signal attenuation is significant. The AD8130 is stable at a gain of 1 and can be used for applications where lower gains are required. Both have user-adjustable gain to help compensate for losses in the transmission line. The gain is set by the ratio of two resistor values. The AD8129/AD8130 have very high input impedance on both inputs, regardless of the gain setting. The AD8129/AD8130 have excellent common-mode rejection (70 dB @ 10 MHz), allowing the use of low cost, unshielded twisted-pair cables without fear of corruption by external noise sources or crosstalk. The AD8129/AD8130 have a wide power supply range from single +5 V to ?12 V, allowing wide common-mode and differential-mode voltage ranges while maintaining signal integrity. The wide common-mode voltage range enables the driver-receiver pair to operate without isolation transformers in many systems where the ground potential difference between drive and receive locations is many volts. The AD8129/AD8130 have considerable cost and performance improvements over op amps and other multiamplifier receiving solutions.

The AD8244 is a precision, low power, FET input, quad unity-gain buffer that is designed to isolate very large source impedances from the rest of the signal chain. The 2 pA maximum bias current, near zero current noise, and 10 T? input impedance introduce almost no error, even with source impedance well into the megaohms.Many traditional operational amplifier pinouts have a supply pin that is next to the noninverting input. A guard trace must be routed between these pins to avoid leakage currents much larger than the bias current of a FET input op amp. Guard traces can be routed between pins for large packages, such as DIP or even SOIC; however, the board area consumed by these packages is prohibitive for many modern applications. The AD8244 solves this problem with a unique pinout that physically separates the high impedance inputs from the low impedance supplies and outputs of the other buffers. This configuration simplifies guarding while reducing board space, allowing high performance and high density in the same design.The AD8244 design is focused on solving problems specific to buffers. This includes close channel-to-channel matching which allows channels of the AD8244 to be used in differential signal chains with minimal error. With its low voltage noise, wide supply range, and high precision, the AD8244 is also flexible enough to provide high performance anywhere a unity-gain buffer is needed, even with low source resistance.The AD8244 is specified over the industrial temperature range of ?40?C to +85?C. It is available in a 10-lead MSOP package.APPLICATIONSBiopotential electrodesMedical instrumentationHigh impedance sensor conditioningFiltersPhotodiode amplifiers

The AD8251 is an instrumentation amplifier with digitally programmable gains that has G? input impedance, low output noise, and low distortion, making it suitable for interfacing with sensors and driving high sample rate analog-to-digital converters (ADCs). It has high bandwidth of 10 MHz, low THD of ?110 dB, and fast settling time of 785 ns (maximum) to 0.001%. Offset drift and gain drift are guaranteed to 1.8 ?V/?C and 10 ppm/?C, respectively, for G = 8. In addition to its wide input common voltage range, it boasts a high common-mode rejection of 80 dB at G = 1 from dc to 50 kHz. The combination of precision dc performance coupled with high speed capabilities makes the AD8251 an excellent candidate for data acquisition. Furthermore, this monolithic solution simplifies design and manufacturing and boosts performance of instrumentation by maintaining a tight match of internal resistors and amplifiers. The AD8251 user interface consists of a parallel port that allows users to set the gain in one of two different ways (see Figure 1 in data sheet for the functional block diagram). A 2-bit word sent via a bus can be latched using the WR input. An alternative is to use transparent gain mode where the state of logic levels at the gain port determines the gain. The AD8251 is available in a 10-lead MSOP package and is specified over the ?40?C to +85?C temperature range, making it an excellent solution for applications where size and packing density are important considerations.

The AD8260 includes a high current driver, usable as atransmitter, and a low noise digitally programmable variablegain amplifier (DGA), useable as a receiver.The receiver section consists of a single-ended input preamplifier,and linear-in-dB, differential-output DGA. The receiver hasa small signal ?3 dB bandwidth of 230 MHz; the driver smallsignal bandwidth is 195 MHz. The driver delivers ?300 mA,well suited for driving low impedance loads, even whenconnected to a 3.3 V supply.The AD8260 DGA is ideal for trim applications and has a gainspan of 30 dB, in 3 dB steps. Excellent bandwidth uniformity ismaintained across the entire frequency range. The low output-referrednoise of the DGA is advantageous in driving highspeed ADCs. The differential output facilitates the interface tomodern low voltage high speed ADCs.Single-supply and dual-supply operation makes the part versatileand enables gain control of negative-going pulses, such as thosegenerated by photodiodes or photo-multiplier tubes, as well asprocessing band-pass signals on a single supply. For maximumdynamic range, it is essential that the part be ac-coupled whenoperating on a single supply.The AD8260 preamplifier (PrA) is configured with externalresistors for gains greater than 6 dB and can be inverting ornoninverting. The DGA is characterized with a noninvertingpreamplifier gain of 2?. The attenuator has a range of 30 dB andthe output amplifier has a gain of 8? (18.06 dB). The lowestnoninverting gain range is ?6 dB to +24 dB and shifts up withincreased preamplifier gain. The gain is controlled via a parallelport (Pin GNS0 to Pin GNS3) with 10 gain steps of 3 dB percode. The preamplifier and DGA are disabled for any code thatis not assigned a gain step.The AD8260 can operate with single or dual supplies from 3.3 Vto ?5 V.

The AD8317 is a demodulating logarithmic amplifier, capable of accurately converting an RF input signal to a corresponding decibel-scaled output. It employs the progressive compression technique over a cascaded amplifier chain, each stage of which is equipped with a detector cell. The device can be used in either measurement or controller modes. The AD8317 maintains accurate log conformance for signals of 1 MHz to 8 GHz and provides useful operation to 10 GHz. The input dynamic range is typically 55 dB (referenced to 50 ?) with less than ?3 dB error. The AD8317 has 6 ns/10 ns response time (fall time/rise time) that enables RF burst detection to a pulse rate of beyond 50 MHz. The device provides unprecedented logarithmic intercept stability vs. ambient temperature conditions. A supply of 3.0 V to 5.5 V is required to power the device. Current consumption is typically 22 mA, and it decreases to 200 ?A when the device is disabled.The AD8317 can be configured to provide a control voltage to a power amplifier or a measurement output from the VOUT pin. Because the output can be used for controller applications, special attention has been paid to minimize wideband noise. In this mode, the setpoint control voltage is applied to the VSET pin.The feedback loop through an RF amplifier is closed via VOUT, the output of which regulates the output of the amplifier to a magnitude corresponding to VSET. The AD8317 provides 0 V to (VPOS ? 0.1 V) output capability at the VOUT pin, suitable for controller applications. As a measurement device, VOUT is externally connected to VSET to produce an output voltage, VOUT, that is a decreasing linear-in-dB function of the RF input signal amplitude.The logarithmic slope is ?22 mV/dB, determined by the VSET interface. The intercept is 15 dBm (referenced to 50 ?, CW input) using the INHI input. These parameters are very stable against supply and temperature variations.The AD8317 is fabricated on a SiGe bipolar IC process and is available in a 2 mm ? 3 mm, 8-lead LFCSP with an operating temperature range of ?40?C to +85?C.Applications RF transmitter PA setpoint control and level monitoring Power monitoring in radio link transmitters RSSI measurement in base stations, WLANs, WiMAX, and radars
