The NCS21801/2/4 are precision op amps featuring low input offset voltage and low offset drift over time and temperature. The common mode voltage range extends 100mV beyond the supply rails, which makes it suitable for both high−side and low−side current sensing applications. The NCS21801/2/4 are available in single, dual, and quad channel configurations. All versions are specified for operation from −40°C to +125°C. NCV prefix parts are automotive grade 1 qualified and offer performance over the extended temperature range from −40°C to +150°C.
