Instrumentation Amp Minimizes Errors While Drawing Just 95 μA

The LT1789-1 micropower instrumentation amplifier features dc performance while drawing just 95 µA (maximum) of supply current. Optimized for low-voltage, single-supply operation, it maintains performance from 2.2 to 36 V. It keeps dc errors to a minimum and eliminates the need for external trim circuitry with its 100-µV maximum input offset voltage, less than 0.5-µV/°C input offset drift, high power-supply rejection, and 100-dB common-mode rejection ratio. Available in an eight-pin surface-mount package, the LT1789-1 is fully specified over the −40°C to 85°C industrial temperature range. Pricing starts at $3.20 each in 1000-piece quantities.
