Description

The MAX44244 / MAX44245 / MAX44248 family of parts provide ultra-precision, low-noise, zero-drift single/quad/dual operational amplifiers featuring very low-power operation with a wide supply range.

The devices incorporate a patented auto-zero circuit that constantly measures and compensates the input offset to eliminate drift over time and temperature as well as the effect of 1/f noise.

These devices also feature integrated EMI filters to reduce high-frequency signal demodulation on the output. The op amps operate from either a single 2.7V to 36V supply or dual ±1.35V to ±18V  supply. The devices are unity-gain stable with a 1MHz gain-bandwidth product and a low 90µA supply current per amplifier.
