Product details

Gain-bandwidth product is 1.6 MHz, supply current is 600 µA per channel.

1 µV offset — the zero-drift payoff

That stability means the error budget stays tight for bridge sensors, medical instrumentation, or any DC-coupled measurement where a few microvolts of drift would swamp the signal. Input bias current is 100 pA, so high-impedance sources like photodiodes or pH probes do not load the node.

The amplifier runs from 2.7 V to 12 V. Rail-to-rail output allows the signal to swing close to the supply rails.

Frequently asked questions

Does OPA2735AIDGKR support rail-to-rail output?

Yes, the output type is rail-to-rail, allowing the signal to swing close to the supply rails.
