Zero-drift precision op-amp

12 August 2015 Analogue, Mixed Signal, LSI

Analog Devices introduced the first in a new series of high-voltage, low-noise, zero-drift, precision operational amplifiers that provide on-chip electromagnetic interference (EMI) filtering and eliminate the need for calibration circuitry. The dual-channel ADA4522-2 operates within a supply voltage range of 4,5 V to 55 V and exhibits typical noise performance of 5,8 nV/√Hz at 1 kHz.

Combining the ease-of-use of a precision op-amp with the ultra-low offset and drift of a zero-drift op-amp, the chip is suitable for a wide range of applications, including current sensing in electronic loads, power supplies and motor control, and offset correction in composite amplifiers used in instrumentation and other applications.
