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 con-  
sumption 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 con-  
sumption make the AD627 ideal for industrial applications,  
including 4 mA-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 keep dc errors to a mini-  
mum in the users system. The AD627 also holds errors over  
frequency to a minimum by providing excellent CMRR over  
frequency. Line noise, as well as line harmonics, will be rejected,  
since the CMRR remains high up to 200 Hz.

The AD627 provides superior performance, uses less circuit  
board area and does it for a lower cost than micropower discrete  
designs.

PRODUCT DESCRIPTION  
AD627  
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 the user  
with excellent ac and dc specifications while operating at only  
85 µA max.

The AD627 offers superior user flexibility by allowing the user  
to set the gain of the device with a single external resistor, and  
by conforming to the 8-lead industry standard pinout configura-  
tion. With no external resistor, the AD627 is configured for a  
gain of 5. With an external resistor, it can be programmed for  
gains of up to 1000.
