NCV21874DTBR2G

Instrumentation, Op Amps, Buffer Amps Overview

The NCV21874DTBR2G is a dual-channel zero-drift operational amplifier manufactured by onsemi. It features a maximum input offset voltage of 52 µV and a drift rate of 0.4 µV/°C. The device operates with a gain-bandwidth product of 350 kHz and a slew rate of 100 mV/µs. Input bias current is limited to 400 pA, while the input voltage noise density is 62 nV/√Hz. It supports a supply voltage range from 1.8 V to 5.5 V, drawing 17 µA per channel. The common-mode rejection ratio reaches 127 dB, and each channel provides an output current of 11 mA. It is housed in a TSSOP-14 package.
