Product details

High-speed voltage-feedback amplifier in a small SC-70-6 package

That combination — wide bandwidth and low quiescent draw — makes it a fit for high-speed signal chains where power budget is tight, such as photodiode front-ends, ADC drivers, or RF IF amplifiers. The rail-to-rail output stage preserves dynamic range on a single 2.7 V to 5.4 V supply. Input offset voltage is trimmed to 15 µV, and input bias current runs 1.5 µA, both typical for a bipolar input stage at this speed grade.

350 V/µs slew rate — what it buys you

A 350 V/µs slew rate supports fast settling for high-speed ADC drivers and pulse amplifiers.

The part is offered in the SC-70-6 package (supplier device package SC-70-6, also described as SC-88 / SOT-363). The operating temperature range spans -40°C to 125°C.

Frequently asked questions

Can OPA838SIDCKT be used as a comparator?

No, the OPA838SIDCKT is a voltage-feedback amplifier, not a comparator. It lacks the open-collector output and propagation delay specifications needed for comparator applications.
