Overview
The OPA187IDBVT is a high-precision, low-power operational amplifier from Texas Instruments. It is part of the OPAx187 series, which utilizes auto-zeroing techniques to provide low offset voltage and near zero drift over time and temperature. This amplifier is designed for applications requiring high accuracy and stability, offering rail-to-rail output operation and a wide supply voltage range. The OPA187IDBVT is available in a microsize 5-pin SOT-23 package, making it suitable for space-constrained designs.
