Product Details
The AD623 is an integrated, single- or dual-supply instrumentation amplifier that delivers rail-to-rail output swing using supply voltages from 3 V to 12 V. 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 of up to 1000.
The superior 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 commonmode voltages as low as 150 mV below ground. The AD623 maintains superior performance with dual and single polarity power supplies.
