Analog Devices launched new a high voltage, low noise, zero drift op amp ADA4523-1 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.
