Product details

What this dual op-amp is built for

Each channel draws 13 µA typical, and the gain-bandwidth product sits at 85 kHz — a combination that tells you this part trades speed for micropower operation. The differential output type suits it for driving balanced lines or feeding a differential-input ADC stage.

It is sized for DC or low-frequency signals where the 85 kHz GBW is ample. The 50 µV typical input offset is tight for a micropower amplifier, reducing the need for software trim in a precision bridge or thermocouple front-end.

Frequently asked questions

What is the gain bandwidth product of MAX478ESA+?

The gain-bandwidth product is 85 kHz, appropriate for low-frequency signal conditioning where micropower operation is the priority.

Is MAX478ESA+ RoHS compliant?

Yes, it is ROHS3 compliant.
