ADA4523-1BCPZ-RL7

ADA4523-1 is a high voltage, low noise, zero drift opamp. It offers precision dc performance over a wide supply range of 4.5V to 36V. The self calibrating circuitry of the device results in low offset voltage drift with temperature (0.01µV/°C maximum) and zero drift over time. Additionally, the device uses on-chip filtering to achieve high immunity to electromagnetic interference (EMI). It is widely used in application such as high resolution data acquisition, reference buffering, test and measurement, electronic scales, thermocouple amplifiers, strain gauges, low-side current sense etc.
