The AD5243 and AD5248 provide a compact 3 mm × 4.9 mmpackaged solution for dual, 256-position adjustment applications.The AD5243 performs the same electronic adjustment functionas a 3-terminal mechanical potentiometer, and the AD5248performs the same adjustment function as a 2-terminal variableresistor. Available in four end-to-end resistance values (2.5 kΩ,10 kΩ, 50 kΩ, and 100 kΩ), these low temperature coefficientdevices are ideal for high accuracy and stability-variableresistance adjustments. The wiper settings are controllablethrough the I2C-compatible digital interface. The AD5248 hasextra package address decode pins, AD0 and AD1, allowingmultiple parts to share the same I2C, 2-wire bus on a PCB. Theresistance between the wiper and either endpoint of the fixedresistor varies linearly with respect to the digital code transferred into the RDAC latch. (The terms digital potentiometer, VR,and RDAC are used interchangeably.)Operating from a 2.7 V to 5.5 V power supply and consumingless than 6 µA allows the AD5243/AD5248 to be used inportable battery-operated applications.For applications that program the AD5243/AD5248 at thefactory, Analog Devices, Inc., offers device programmingsoftware running on Windows® NT/2000/XP operating systems.This software effectively replaces the need for external I2Ccontrollers, which in turn enhances the time to market ofsystems. An AD5243/AD5248 evaluation kit and software areavailable. The kit includes a cable and instruction manual.Applications Systems calibrations Electronics level settings Mechanical trimmers replacement in new designs Permanent factory printed circuit board (PCB) setting Transducer adjustment of pressure, temperature, position, chemical, and optical sensors RF amplifier biasing Gain control and offset adjustment

Demonstration circuit 1697A features the LTC2945. The LTC2945 is a rail-to-rail system monitor that measures current, voltage, and power. It features an operating range of 2.7V to 80V and includes a shunt regulator for supplies above 80V to allow flexibility in the selection of input supply. The current common mode measurement range of 0V to 80V is independent of the input supply. An onboard 0.75% accurate 12-bit ADC measures load current, input voltage and an auxiliary external voltage. A 24-bit power value is generated by digitally multiplying the measured 12-bit load current and input voltage data. Minimum and maximum values are stored and an overrange alert with programmable thresholds minimizes the need for software polling. Data is reported via a standard I2C interface. The demo board is populated for a 5A application. This can be changed by populating R1 accordingly.

The ADM3061E/ADM3062E/ADM3063E/ADM3064E/ADM3065E/ADM3066E/ADM3067E/ADM3068E are 3.0 V to5.5 V, IEC electrostatic discharge (ESD) protected RS-485transceivers, allowing the devices to withstand ?12 kV contactdischarges on the transceiver bus pins without latch-up ordamage. The ADM3062E/ADM3064E/ADM3066E/ADM3068Efeature a VIO logic supply pin that allows a flexible digital interfacecapable of operating as low as 1.62 V. The ADM3065E/ADM3066E/ADM3067E/ADM3068E aresuitable for high speed, 50 Mbps, bidirectional data communication on multipoint bus transmission lines. The ADM3061E/ADM3062E/ADM3063E/ADM3064E/ADM3065E/ADM3066E/ADM3067E/ADM3068E feature a 1/4 unit load inputimpedance that allows up to 128 transceivers on a bus. TheADM3061E/ADM3062E/ADM3063E/ADM3064E models offerall of the same features as the ADM3065E/ADM3066E/ADM3067E/ADM3068E models at a low 500 kbps data rate thatis suitable for operation over long cable runs. The ADM3061E/ADM3062E/ADM3065E/ADM3066E are halfduplex RS-485 transceivers, fully compliant to the PROFIBUS?standard with increased 2.1 V bus differential voltage at VCC ?4.5 V. The ADM3063E/ADM3064E/ADM3067E/ADM3068Eare full duplex RS-485 transceiver options. The RS-485 transceivers are available in a number of spacesaving packages, including the 10-lead, 3 mm ? 3 mm lead framechip-scale package (LFCSP), the 8-lead or 10-lead, 3 mm ? 3 mmmini small outline package (MSOP), and the 8-lead or 14-lead,narrow body standard small outline packages (SOIC_N).Models with operating temperature ranges of ?40?C to +125?Cand ?40?C to +85?C are available. Excessive power dissipation caused by bus contention or byoutput shorting is prevented by a thermal shutdown circuit. If asignificant temperature increase is detected in the internal drivercircuitry during fault conditions, this feature forces the driveroutput into a high impedance state. The ADM3061E/ADM3062E/ADM3063E/ADM3064E/ADM3065E/ADM3066E/ADM3067E/ADM3068E guarantee alogic high receiver output when the receiver inputs are shorted,open, or connected to a terminated transmission line with alldrivers disabled.

The AD9523-1 provides a low power, multi-output, clock distribution function with low jitter performance, along with an on-chip PLL and VCO with two VCO dividers. The on-chip VCO tunes from 2.94 GHz to 3.1 GHz.The AD9523-1 is designed to support the clock requirements for long term evolution (LTE) and multicarrier GSM base station designs. It relies on an external VCXO to provide the reference jitter cleanup to achieve the restrictive low phase noise requirements necessary for acceptable data converter SNR performance.The input receivers, oscillator, and zero delay receiver provide both single-ended and differential operation. When connected to a recovered system reference clock and a VCXO, the device generates 14 low noise outputs with a range of 1 MHz to 1 GHz, and one dedicated buffered output from the input PLL (PLL1). The frequency and phase of one clock output relative to another clock output can be varied by means of a divider phase select function that serves as a jitter-free, coarse timing adjustment in increments that are equal to half the period of the signal coming out of the VCO.An in-package EEPROM can be programmed through the serial interface to store user-defined register settings for power-up and chip reset.APPLICATIONS LTE and multicarrier GSM base stations Wireless and broadband infrastructure Medical instrumentation Clocking high speed ADCs, DACs, DDSs, DDCs, DUCs, MxFEs Low jitter, low phase noise clock distribution Clock generation and translation for SONET, 10Ge, 10G FC, and other 10 Gbps protocols Forward error correction (G.710) High performance wireless transceivers ATE and high performance instrumentation
