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
