Instrumentation Amplifier Works On Supplies As Low As 2.7 V

The LTC2053 zero-drift instrumentation amplifier features a rail-to-rail input and output. It works on a single 3-V supply and features a maximum offset voltage of 10 µV. While the offset drift is 50 nV/°C, the LTC2053 features a high common-mode rejection ratio of 116 db, which is gain-independent. Gain error is less than 0.01% and gain nonlinearity is less than 10 ppm. The LTC2053's differential inputs operate from rail-to-rail and the output swings rail-to-rail. Operating with single or split supplies from 2.7 to ±11 V, this amplifier draws less than a 1-mA supply current. It's guaranteed to operate from −40°C to 85°C and comes in a tiny MSOP-8 package. In 1000-unit quantities, pricing for the LTC2053 starts at $3.20 each.
