Product details

Zero-drift precision in a SOT-23-5 footprint

The Microchip MCP6V91UT-E/OT is a single-supply, zero-drift operational amplifier in a 5-pin SOT-23-5 package. Its 9 µV maximum input offset voltage and 2 pA input bias current suit it for precision DC signal chains where drift over temperature would otherwise require periodic system calibration — weigh scales, bridge transducers, thermocouple amplifiers, and photodiode front-ends.

Rail-to-rail output swings within millivolts of each supply, preserving dynamic range at low voltages.

The extended industrial temperature range qualifies the part for under-hood automotive, factory-floor automation, outdoor telecom nodes, and engine-bay electronics where commercial 85°C parts would derate or fail. The active product status means Microchip continues to manufacture it — no last-time-buy clock is running, and it remains eligible for new-design qualification.

Frequently asked questions

What is MCP6V91UT-E/OT's listed slew rate?

The datasheet specifies a 9.5 V/µs slew rate for the MCP6V91UT-E/OT, which is unusually fast for a zero-drift amplifier and supports moderate-speed signal conditioning up to roughly 1 MHz closed-loop gain.

Is MCP6V91UT-E/OT a good replacement for OPA333?

Both are single-supply zero-drift op-amps in SOT-23-5 packages, but the MCP6V91UT-E/OT offers a 10 MHz gain-bandwidth versus OPA333's 350 kHz, and a 9.5 V/µs slew rate versus 0.16 V/µs — a significant speed upgrade. The input offset voltage is comparable (9 µV vs OPA333's 10 µV). Pin compatibility should be verified against the specific layout, but the electrical performance envelope is a superset.
