MCP6021 — Datasheet Summary, Specs & Alternatives

01 — Overview

This Microchip datasheet covers the MCP6021/1R/2/3/4 family of rail-to-rail input/output operational amplifiers. It details electrical characteristics, package options, and application examples for single and quad configurations across industrial and extended temperature ranges. Key performance parameters include a typical 10 MHz bandwidth, low noise of 8.7 nV/√Hz at 10 kHz, and an input offset voltage maximum of ±500 µV for industrial parts. The devices operate on a supply voltage range of 2.5 V to 5.5 V with a typical current consumption of 1 mA. They are unity gain stable and feature high power supply rejection ratios up to 90 dB.
