3 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 m V of the rails into high-impedance loads. The input mon-mode range includes the...
