The OPA2376AIDGKR from Texas Instruments is a dual-channel precision CMOS operational amplifier using TI’s proprietary e-trim technology to achieve outstanding DC precision without chopper artifacts. It offers 25μV max input offset voltage, 0.32μV/°C drift, 7.5nV/√Hz voltage noise at 1kHz, and 5.5MHz gain bandwidth product, all from just 760μA per channel. The rail-to-rail input and output stages operate from a 2.2V to 5.5V single supply, making it ideal for precision portable and battery-powered applications. The EMI-hardened input stage reduces susceptibility to RF interference.

The OPA2376 uses a CMOS input stage with TI’s e-trim technology, which performs precision trimming of the input offset voltage during final wafer test, achieving 25μV max offset without the switching artifacts associated with chopper-stabilized amplifiers. The rail-to-rail input stage uses complementary PMOS and NMOS differential pairs that cover the entire supply range. The output stage is a rail-to-rail class AB CMOS push-pull capable of swinging within 10mV of either rail. Internal frequency compensation ensures stability in unity-gain configurations. The 5.5MHz GBW and 2V/μs slew rate provide adequate bandwidth and settling for precision signal conditioning.
