The ADA4523-1 is a high voltage, low noise, zero drift op amp
that offers precision dc performance over a wide supply range of
4.5 V to 36 V. Offset voltage and 1/f noise are suppressed,
allowing this op amp to achieve a maximum offset voltage of
±4 µV and a 0.1 Hz to 10 Hz input noise voltage of 88 nV p-p
typical. The self calibrating circuitry of the ADA4523-1 results in
low offset voltage drift with temperature (0.01 µV/°C maximum)
and zero drift over time. Additionally, the ADA4523-1 uses
on-chip filtering to achieve high immunity to electromagnetic
interference (EMI).
Wide supply range, combined with low noise, low offset, 168 dB
power supply rejection ratio (PSRR), and 160 dB common-mode
rejection ratio (CMRR), make the ADA4523-1 well suited for high
dynamic range test, measurement, and instrumentation systems. Rev. 0 R2 …
