About Instrument Amplifier, 1 Amplifier, 200 µV, 0.3
AD623 Single-Supply Rail-to-Rail Instrumentation Amplifier The AD623 is an integrated single-supply instrumentation amplifier that delivers rail-to-rail output swing on a 3V to 12V supply. The AD623 offers superior 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 up to 1000. The AD623 holds errors to a minimum by providing superior AC CMRR that increases with increasing gain. Line noise, as well as line harmonics, are rejected because the CMRR remains constant up to 200 Hz. The AD623 has a wide input common-mode range and can amplify signals that have a common-mode voltage 150 mV below ground. Although the design of the AD623 was optimized to operate from a single supply, the AD623 still provides superior performance when operated from a dual voltage supply (+/- 2.5 V to +/- 6.0 V). Features Easy to use Higher performance than discrete design Low power, 550uA max supply current Applications Low power medical instrumentation Transducer interfaces Thermocouple amplifiers Industrial process controls Difference amplifiers Low power data acquisition
