Analog Devices Inc. ADA4522 Operational Amplifiers

Analog Devices ADA4522 Operational Amplifiers include Single Channel (ADA4522-1), Dual Channel (ADA4522-2), and Quad Channel (ADA4522-4) Op Amps. These zero-drift Op Amps operate in a 4.5V to 55V supply voltage range, exhibit exceptional noise performance and are optimized for total accuracy over time, temperature, and voltage conditions. The design combines the ease-of-use of a precision operational amplifier with the extremely low offset and drift of a zero-drift Op Amp. ADA4522 Op Amps minimize system noise, board space, and development time by using on-chip electromagnetic interference (EMI) filtering and eliminating the requirement for calibration circuitry.

The ADA4522-1, ADA4522-2, and ADA4522-4 Op Amps are fully specified over the extended industrial temperature range of -40°C to +125°C. These devices are offered in 8-lead MSOP, 8-lead SOIC, 14-lead SOIC, and 14-lead TSSOP packages for design flexibility.
