GENERAL DESCRIPTION

The AD623 is an integrated single-supply instrumentation

amplifier that delivers rail-to-rail output swing on a 3 V to 12 V

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.

Single-Supply, Rail-to-Rail, Low Cost

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).

Low power consumption (1.5 mW at 3 V), wide supply voltage

range, and rail-to-rail output swing make the AD623 ideal

for battery-powered applications. The rail-to-rail output stage

maximizes the dynamic range when operating from low supply

voltages. The AD623 replaces discrete instrumentation amplifier

designs and offers superior linearity, temperature stability, and

reliability in a minimum of space.
