The AD620 is a low cost, high accuracy instrumentation amplifier that requires only one external resistor to set gains of 1 to 10,000. Furthermore, the AD620 features 8-lead SOIC and DIP packaging that is smaller than discrete designs and offers lower power (only 1.3 mA max supply current), making it a good fit for battery powered, portable (or remote) applications.The AD620, with its high accuracy of 40 ppm maximum nonlinearity, low offset voltage of 50 µV max, and offset drift of 0.6 µV/°C max, is ideal for use in precision data acquisition systems, such as weigh scales and transducer interfaces. Furthermore, the low noise, low input bias current, and low power of the AD620 make it well suited for medical applications such as ECG and noninvasive blood pressure monitors.The low input bias current of 1.0 nA max is made possible with the use of Superϐeta processing in the input stage. The AD620 works well as a preamplifier due to its low input voltage noise of 9 nV/√Hz at 1 kHz, 0.28 μV p-p in the 0.1 Hz to 10 Hz band, and 0.1 pA/√Hz input current noise. Also, the AD620 is well suited for multiplexed applications with its settling time of 15 μs to 0.01%, and its cost is low enough to enable designs with one in-amp per channel.APPLICATIONSWeigh scalesECG and medical instrumentationTransducer interfaceData acquisition systemsIndustrial process controlsBattery-powered and portable equipment

The AD623 is an integrated, single- or dual-supply instrumentation amplifier that delivers rail-to-rail output swing using supply voltages from 2.7 V to 12 V. The AD623 offers user flexibility by allowing single gain set resistor programming and by conforming to the 8-lead industry standard pinout configuration. With no external resistor, the AD623 is configured for unity gain (G = 1), and with an external resistor, the AD623 can be programmed for gains of up to 1000.The accuracy of the AD623 is the result of increasing ac common-mode rejection ratio (CMRR) coincident with increasing gain. Line noise harmonics are rejected due to constant CMRR up to 200 Hz. The AD623 has a wide input common-mode range and amplifies signals with common-mode voltages as low as 150 mV below ground. The AD623 maintains optimal performance with dual and single polarity power supplies.Applications Low power medical instrumentation Transducer interfaces Thermocouple amplifiers Industrial process controls Difference amplifiers Low power data acquisition

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.
