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.

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.
