common-mode range and can amplify signals that have a  
common-mode voltage 150 mV below ground. Although the  
design of the AD623 has been 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 maxi-  
mizes the dynamic range when operating from low supply volt-  
ages. The AD623 replaces discrete instrumentation amplifier  
designs and offers superior linearity, temperature stability and  
reliability in a minimum of space. Until the AD623, this level of  
instrumentation amplifier performance has not been achieved.

PRODUCT DESCRIPTION  
x100  
The AD623 is an integrated single supply instrumentation am-  
plifier that delivers rail-to-rail output swing on a single supply  
(+3 V to +12 V supplies). The AD623 offers superior user flex-  
ibility by allowing single gain set resistor programming, and  
conforming to the 8-lead industry standard pinout configura-  
tion. 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 1,000.

The AD623 holds errors to a minimum by providing superior  
AC CMRR that increases with increasing gain. Line noise, as  
well as line harmonics, will be rejected since the CMRR re-  
mains constant up to 200 Hz. The AD623 has a wide input
