Product Overview
The OPA2376 is a Texas Instruments dual precision operational amplifier in the Signal_Chain category. The OPA2376 dual version provides two amplifier channels with rail-to-rail input and output operation, supporting a recommended supply range of 2.2 to 5.5 V or a nominal dual-supply equivalent of ±1.1 to ±2.75 V.
Precision parameters include 5 µV typical and 25 µV maximum input offset voltage at 25 °C, 0.26 µV/°C typical drift from -40 °C to +85 °C, and 0.32 µV/°C typical drift from -40 °C to +125 °C. Noise specifications include 0.8 µVPP from 0.1 Hz to 10 Hz and 7.5 nV/√Hz voltage noise density at 1 kHz.
Package options for OPA2376 include SOIC-8, VSSOP-8, and DSBGA-8. Thermal resistance junction-to-ambient is specified as 111.1 °C/W for SOIC, 171.2 °C/W for VSSOP, and 119.2 °C/W for DSBGA. Applications should account for absolute maximum limits, ESD ratings, output swing, short-circuit current, and the -40 to 150 °C recommended operating temperature range.
