RF Amplifier IF amp 20 dB Gain

The AD848 and AD849 are high speed, low power monolithic operational amplifiers. The AD848 is internally compensated so that it is stable for closed loop gains of 5 or greater. The AD849 is fully decompensated and is stable at gains greater than 24. The AD848 and AD849 achieve their combination of fast ac and good dc performance by utilizing Analog Devices' junction isolated complementary bipolar (CB) process. This process enables these op amps to achieve their high speed while only requiring 4.8 mA of current from the power supplies.The AD848 and AD849 are members of Analog Devices' family of high speed op amps. This family includes, among others, the AD847 which is unity gain stable, with a gain bandwidth of 50 MHz. For more demanding applications, the AD840, AD841 and AD842 offer even greater precision and greater output current drive.The AD848 and AD849 have good dc performance. When operating with ±5 V supplies, they offer open loop gains of 13 V/mV (AD848 with a 500 Ohm load) and low input offset voltage of 1 mV maximum. Common-mode rejection is a minimum of 92 dB. Output voltage swing is ±3 V even into loads as low as 150 Ohm.

The AD8522 is a complete dual 12-bit, single-supply, voltage output DAC in a 14-pin DIP, or SO-14 surface mount package. Fabricated in a CBCMOS process, features include a serial digital interface, onboard reference, and buffered voltage output. Ideal for +5 V-only systems, this monolithic device offers low cost and ease of use, and requires no external components to realize the full performance of the device.The serial digital interface allows interfacing directly to numerous microcontroller ports, with a simple high speed, three-wire data, clock, and load strobe format. The 16-bit serial word contains the 12-bit data word and DAC select address, which is decoded internally or can be decoded externally using LDA, LDB inputs. A serial data output allows the user to easily daisy-chain multiple devices in conjunction with a chip select input. A reset RS input sets the outputs to zero scale or midscale, as determined by the input MSB.The output 4.095 V full scale is laser trimmed to maintain accuracy over the operating temperature range of the device, and gives the user an easy-to-use one-millivolt-per-bit resolution. A 2.5 V reference output is also available externally for other data acquisition circuitry, and for ratiometric applications. The output buffers are capable of driving ±5 mA.The AD8522 is available in the 14-pin plastic DIP and low profile 1.5 mm SOIC-14 packages.APPLICATIONS Digitally Controlled Calibration Servo Controls Process Control Equipment Computer Peripherals Portable Instrumentation Cellular Base Stations Voltage Adjustment

The AD8582 is a complete, parallel input, dual 12-bit, voltage output DAC designed to operate from a single +5 volt supply. Built using a CBCMOS process, this monolithic DAC offers the user low cost, and ease-of-use in +5 volt only systems.Included on the chip, in addition to the DACs, are a rail-to-rail amplifier, latch and reference. The reference (VREF) is trimmed to 2.5 volts output, and the on-chip amplifier gains up the DAC output to 4.095 volts full scale. The user needs only supply a +5 volt supply.>/p>The AD8582 is coded natural binary. The op amp output swings from 0 volt to +4.095 volts for a one-millivolt-per-bit resolution, and is capable of driving ±5 mA. Operation down to 4.3 V is possible with output load currents less than 1 mA.The high speed parallel data interface connects to the fastest processors without wait states. The double-buffered input structure allows the user to load the input registers one at a time, then a single load strobe tied to both LDA + LDB inputs will update both DAC outputs simultaneously. LDA and LDB can also be activated independently to immediately update their respective DAC registers. An address input decodes DAC A or DAC B when the chip select CS input is strobed. An asynchronous reset input sets the output to zero scale. The MSB bit can be used to establish a preset to midscale when the reset input is strobed.The AD8582 is available in the 24-pin plastic DIP and the surface mount SOIC-24. Each part is fully specified for operation over -40°C to +85°C, and the full +5 V ±5% power supply range.

The 12-channel AD8802 / AD8804 provides independent digitally-controllable voltage outputs in a compact 20-lead package. This potentiometer divider TrimDAC® allows replacement of the mechanical trimmer function in new designs. The AD8802 / AD8804 is ideal for dc voltage adjustment applications.Easily programmed by serial interfaced microcontroller ports, the AD8802 with its midscale preset is ideal for potentiometer replacement where adjustments start at a nominal value. Applications such as gain control of video amplifiers, voltage controlled frequencies and bandwidths in video equipment, geometric correction and automatic adjustment in CRT computer graphic displays are a few of the many applications ideally suited for these parts. The AD8804 provides independent control of both the top and bottom end of the potentiometer divider allowing a separate zero-scale voltage setting determined by the VREFL pin. This is helpful for maximizing the resolution of devices with a limited allowable voltage control range.Internally the AD8802/AD8804 contains 12 voltage-output digital-to-analog converters, sharing a common reference-voltage input.Each DAC has its own DAC latch that holds its output state. These DAC latches are updated from an internal serial-to-parallel shift register that is loaded from a standard 3-wire serial input digital interface. The serial-data-input word is decoded where the first 4 bits determine the address of the DAC latches to be loaded with the last 8 bits of data. The AD8802/ AD8804 consumes only 10 µA from 5 V power supplies. In addition, in shutdown mode reference input current consumption is also reduced to 10 µA while saving the DAC latch settings for use after return to normal operation.The AD8802 / AD8804 is available in the 20-pin plastic DIP, the SOIC-20 surface mount package, and the 1 mm thin TSSOP-20 package.APPLICATIONS Automatic Adjustment Trimmer Replacement Video and Audio Equipment Gain and Offset Adjustment Portable and Battery Operated Equipment
