The OPA4180ID is a quad low noise Operational Amplifier uses zero-drift techniques to simultaneously provide low offset voltage (75μV), near zero-drift over time and temperature. This miniature, high-precision, low quiescent current amplifier offers high input impedance and rail-to-rail output swing within 18mV of the rails. The input common-mode range includes the negative rail.
RFI filtered inputs
Excellent DC precision - 126dB PSRR, 114dB CMRR and 120dB open-loop gain (AOL)
