AD8221 Precision Instrumentation Amplifier

ADI’s AD8221 is a high-performance instrumentation amplifier that is gain programmable. This amp can operate in either with a single voltage supply of 4.6 V to 36 V or dual supply of +2.3 V to +18 V and requires 900 μA of current. The amplifier maintains a minimum CMRR of 80 dB to 10 kHz for grades at G = 1. The high CMRR allows for the rejection of wideband interference and line harmonics which reduces filter requirement for board and cost savings. This amp has a temperature range of -40°C to +85°C and comes in 8-pin MSOP or SOIC package. The AD8221 is an excellent choice for an instrumentation amplifier for medical, industrial, and precision applications.
