GENERAL DESCRIPTION
The AD627 is an integrated, micropower instrumentation
amplifier that delivers rail-to-rail output swing on single and
dual (+2.2 V to ±18 V) supplies. The AD627 provides excellent
ac and dc specifications while operating at only 85 μA maximum.
The AD627 offers superior flexibility by allowing the user to set
the gain of the device with a single external resistor while con-
forming to the 8-lead industry-standard pinout configuration.
With no external resistor, the AD627 is configured for a gain of 5.
With an external resistor, it can be set to a gain of up to 1000.
A wide supply voltage range (+2.2 V to ±18 V) and micropower
current consumption make the AD627 a perfect fit for a wide
range of applications. Single-supply operation, low power
consumption, and rail-to-rail output swing make the AD627

Rail-to-Rail Instrumentation Amplifier
Micropower, Single- and Dual-Supply,
ideal for battery-powered applications. Its rail-to-rail output
stage maximizes dynamic range when operating from low
supply voltages. Dual-supply operation (±15 V) and low power
consumption make the AD627 ideal for industrial applications,
including 4 to 20 mA loop-powered systems.
The AD627 does not compromise performance, unlike other
micropower instrumentation amplifiers. Low voltage offset,
offset drift, gain error, and gain drift minimize errors in the
system. The AD627 also minimizes errors over frequency by
providing excellent CMRR over frequency. Because the CMRR
remains high up to 200 Hz, line noise and line harmonics are
rejected.
The AD627 provides superior performance, uses less circuit
board area, and costs less than micropower discrete designs.
