📥 Download Datasheet

General Description

The OPAx187 series operational amplifiers use autozeroing techniques to simultaneously provide lowoffset voltage (1 µV), and near zero drift over time and temperature.

These miniature, high-precision, low-quiescent current amplifiers offer high-input impedance and rail-to-rail output swing within 5 mV of the rails into high-impedance loads.

The input common-mode range includes the negative rail.
