Product details

160 V/µs slew rate on 250 µA — the trade-off that defines this part

That combination — fast edge response without burning the power budget — makes it a fit for signal-conditioning stages in battery-operated instrumentation, portable medical gear, or multi-channel data-acquisition front ends where every milliwatt counts. The rail-to-rail output swings close to the supply rails, useful when driving a single-supply ADC input directly.

Package and temperature — board-fit checklist

For the BOM planner, that means no end-of-life notice looming, no last-time-buy scramble, and no forced redesign cycle. It is a current-production part you can qualify into a new design with confidence that supply will hold through the product's run.

Frequently asked questions

Does OPA2835IRMCT support rail-to-rail output?

Yes, the output type is differential, rail-to-rail, allowing the output to swing close to the supply rails — useful for driving single-supply ADCs.

What is the closest alternative to OPA2835IRMCT?

The OPA4374AIPWT is a quad CMOS op-amp with a 6.5 MHz GBW and 5 V/µs slew rate, but it draws 600 µA per channel and runs on 2.7 V minimum. For a dual-channel part with higher speed, the TLV9362IDDFR offers 10.6 MHz GBW and 25 V/µs slew rate but consumes 2.6 mA per channel. Neither is a drop-in replacement — the OPA2835's combination of 160 V/µs slew rate and 250 µA per channel is unique in this package.
