It offers 25\u03bcV max input offset voltage, 0.32\u03bcV\/\u00b0C drift, 7.5nV\/\u221aHz voltage noise at 1kHz, and 5.5MHz gain bandwidth product, all from just 760\u03bcA 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.","working_principle":"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 25\u03bcV 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\/\u03bcs slew rate provide adequate bandwidth and settling for precision signal conditioning.","pin_description":"
