Strain gages  
Low voltage offset, low offset drift, low gain drift, high gain  
accuracy, and high CMRR make this part an excellent choice  
in applications that demand the best dc performance possible,  
such as bridge signal conditioning.  
Transducer interfaces  
Programmable gain affords the user design flexibility. A single  
resistor sets the gain from 1 to 1000. The AD8221 operates on  
both single and dual supplies and is well suited for applications  
where 10 V input voltages are encountered.  
GENERAL DESCRIPTION  
The AD8221 is a gain programmable, high performance  
instrumentation amplifier that delivers the industrys highest  
CMRR over frequency in its class. The CMRR of instrumentation  
amplifiers on the market today falls off at 200 Hz. In contrast,  
the AD8221 maintains a minimum CMRR of 80 dB to 10 kHz  
for all grades at G = 1. High CMRR over frequency allows the  
AD8221 to reject wideband interference and line harmonics,  
greatly simplifying filter requirements. Possible applications  
include precision data acquisition, biomedical analysis, and  
aerospace instrumentation.  
The AD8221 is available in a low cost 8-lead SOIC and 8-lead  
MSOP, both of which offer the industrys best performance. The  
MSOP requires half the board space of the SOIC, making it ideal  
for multichannel or space-constrained applications.  
Performance is specified over the entire industrial temperature  
range of −40°C to +85°C for all grades. Furthermore, the AD8221  
is operational from −40°C to +125°C1.

85°C to 125°C.
