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 conforming 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 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.

An instrumentation amplifier (IA) is used to provide a large amount of gain for very low-level signals, often in the presence of high noise levels. The major properties of IAs are high gain, large common-mode rejection ratio (CMRR), and very high input impedance.
Features include very low DC offset, low drift, low noise, very high open-loop gain, very large common-mode rejection ratio, and high input impedance. Instrumentation amplifiers are used in circuits that require very high accuracy and stability.
The output impedance of the instrumentation amplifier is the output impedance of the difference amplifier, which is very low. The CMRR of the op-amp 3 is very high and almost all of the common mode signal will be rejected.
