The AD623 is an integrated, single- or dual-supply instrumentation amplifier that delivers rail-to-rail output swing using supplyvoltages from 3 V to 12 V. The AD623 offers superior userflexibility by allowing single gain set resistor programming and byconforming 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 beprogrammed for gains of up to 1000.
The superior accuracy of the AD623 is the result of increasingac common-mode rejection ratio (CMRR) coincident withincreasing gain; line noise harmonics are rejected due toconstant CMRR up to 200 Hz. The AD623 has a wide inputcommon-mode range and amplifies signals with commonmodevoltages as low as 150 mV below ground. The AD623maintains superior performance with dual and single polaritypower supplies.
