The AD8221 is a gain programmable, high performance instru-
mentation amplifier that delivers the industry’s highest CMRR
over frequency. 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.
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.

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.
The AD8221 is available in low cost 8-lead SOIC and MSOP
packages, both of which offer the industry’s 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
