NCV21671SQ200T2G

Instrumentation, Op Amps, Buffer Amps Overview

The NCV21671SQ200T2G is a voltage output current shunt monitor manufactured by onsemi. It features a single channel with a fixed gain of 200 V/V. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports a common-mode voltage from -100 mV to 40 V. Key electrical specifications include an input offset voltage of 2 uV, input bias current of 35 uA, and a 3dB bandwidth of 20 kHz. It exhibits a CMRR of 134 dB and a PSRR of 1 uV/V. The amplifier draws 80 uA of operating current and provides rail-to-rail output. It is housed in an SC-70-6 package and functions across temperatures from -40 C to +150 C.
