OPA2392YBJT

The OPAx392 series operational amplifiers (OPAx392, OPA2392, and OPA4392) feature ultra-low offset voltage, temperature drift, and input bias current, enabling rail-to-rail input and output. In addition to precise DC accuracy, the AC performance is optimized for low noise and fast-stable transient response. Thanks to these features, the OPAx392 is an ideal choice for driving high-precision analog-to-digital converters (ADCs) or buffering the outputs of high-resolution digital-to-analog converters (DACs). The OPAx392 uses TI's e-trim™ operational amplifier technology, which can achieve ultra-low offset voltage and offset voltage temperature drift without any input chopping or auto-zeroing techniques. This technology can achieve ultra-low input bias current for sensor input or photodiode current-to-voltage measurement, thereby creating a high-performance transimpedance stage for optical modules or medical instruments.
