Product details

Dual op-amp with 1 µV offset and rail-to-rail output

Each of the two amplifiers draws 420 µA supply current, so the total quiescent for the pair stays under 1 mA.

For a 1 V peak-to-peak output step, the slew rate limits the full-power bandwidth to about 600 kHz — fine for audio processing, motor-current sensing loops, and low-frequency data acquisition. The 300 pA input bias current is low enough that high-impedance sources (10 kΩ or higher) won't introduce significant offset error.

Output drive and supply flexibility

The 2.7 V minimum supply means the part runs on a single lithium-ion cell or a 3.3 V rail, while the 36 V maximum lets it work in 24 V industrial systems without a secondary regulator.

Frequently asked questions

Can MAX44246AUA+T operate from a single 5V supply?

Yes. The rail-to-rail output stage delivers a swing within millivolts of the 5 V rail, preserving dynamic range in a single-supply design.
