The AD8556 is a zero-drift, sensor signal amplifier withdigitally programmable gain and output offset. Designed toeasily and accurately convert variable pressure sensor andstrain bridge outputsto a well-defined output voltage range,the AD8556 accurately amplifies many other differential orsingle-ended sensor outputs. The AD8556 uses the ADIpatented low noise auto-zero and DigiTrim? technologies tocreate an incredibly accurate and flexible signal processingsolution in a very compact footprint.Gain is digitally programmable in a wide range from 70 to1,280 through a serial data interface. Gain adjustment canbe fully simulated in-circuit and then permanently programmedwith reliable polyfuse technology. Output offsetvoltage is also digitally programmable and is ratiometric to thesupply voltage. AD8556 also features internal EMI filters on theVNEG, VPOS, FILT and VCLAMP pins.In addition to extremely low input offset voltage, low inputoffset voltage drift, and very high dc and ac CMRR, the AD8556 also includes a pull-up current source at the input pinsand a pull-down current source at the VCLAMP pin. Thisallows open wire and shorted wire fault detection. A low-passfilter function is implemented via a single low cost externalcapacitor. Output clamping set via an external reference voltageallows the AD8556 to drive lower voltage ADCs safely andaccurately.When used in conjunction with an ADC referenced to the samesupply, the system accuracy becomes immune to normal supplyvoltage variations. Output offset voltage can be adjusted with aresolution of better than 0.4% of the difference between VDDand VSS. A lockout trim after gain and offset adjustmentfurther ensures field reliability.The AD8556 is fully specified from ?40?C to +140?C.Operating from single-supply voltages of 2.7 V to 5.5 V, theAD8556 is offered in the 8-lead SOIC_N, and 4 mm ? 4 mm16-lead LFCSP_VQ.ApplicationsAutomotive SensorsPressure and Position SensorsPrecision Current SensingStrain Gages

The HMC561LP3(E) is a x2 active broadband frequency multiplier utilizing GaAs PHEMT technology in a leadless RoHS compliant SMT package. When driven by a +5 dBm signal, the multiplier provides +14 dBm typical output power from 8 to 21 GHz and the Fo and 3Fo isolations are 15 dBc at 16 GHz. The HMC561LP3(E) is ideal for use in LO multiplier chains for Pt to Pt & VSAT Radios yielding reduced parts count vs. traditional approaches.The low additive SSB Phase Noise of -139 dBc/Hz at 100 kHz offset helps maintain good system noise performance. The RoHS packaged HMC561LP3(E) eliminates the need for wire bonding, and allows the use of surface mount manufacturing techniques.APPLICATIONS Clock Generation Applications:?

The AD5273 is a 64-position, one-time programmable (OTP) digital potentiometer4 that employs fuse link technology to achieve permanent program setting. This device performs the same electronic adjustment function as most mechanical trimmers and variable resistors. It allows unlimited adjustments before permanently setting the resistance values. The AD5273 is programmed using a 2-wire, I2C?-compatible digital control. During write mode, a fuse blow command is executed after the final value is determined, thereby freezing the wiper position at a given setting (analogous to placing epoxy on a mechanical trimmer). When the permanent setting is achieved, the value does not change, regardless of the supply variations or environ-mental stresses under normal operating conditions. To verify the success of permanent programming, Analog Devices, Inc., patterned the OTP validation such that the fuse status can be discerned from two validation bits in the read mode.In addition, for applications that program the AD5273 at the factory, Analog Devices offers device programming software2 running on Windows NT?, Windows? 2000, and Windows XP operating systems. This software application effectively replaces any external I2C controllers, which in turn enhances the user system?s time-to-market.The AD5273 is available in 1 k?, 10 k?, 50 k?, and 100 k? resistances and in a compact 8-lead SOT-23 standard package. It operates from ?40?C to +105?C. Along with its unique OTP feature, the AD5273 lends itself well to general digital potentiometer applications due to its effective resolution, array resistance options, small footprint, and low cost.An AD5273 evaluation kit and software are available. The kit includes the connector and cable that can be converted for factory programming applications.For applications that require dynamic adjustment of resistance settings with nonvolatile EEMEM, refer to the AD5231, AD5232, AD5233, and AD5235?family, and the AD5251, AD5252, AD5254, AD5258, and AD5259?family of nonvolatile memory digital potentiometers.APPLICATIONS System calibrations Electronics level settings Mechanical potentiometers and trimmer replacement Transducer circuit adjustments Programmable filters up to 6 MHz BW31 OTP allows unlimited adjustments before permanent setting. 2 Analog Devices cannot guarantee the software to be 100% compatible to all systems due to the wide variation in computer configurations. 3 Applies to 1 k? parts only. 4 The terms digital potentiometer, VR, and RDAC are used interchangeably.
