MCP6021-E/SN

Instrumentation, Op Amps, Buffer Amps Overview

The MCP6021-E/SN is a single-channel, rail-to-rail input/output operational amplifier from Microchip Technology. It operates on a single supply voltage ranging from 2.5V to 5.5V and features a typical gain-bandwidth product of 10 MHz with a slew rate of 7 V/µs. The device exhibits low noise (8.7 nV/√Hz at 10 kHz) and low total harmonic distortion (0.00053% at G=1). Industrial temperature variants specify a maximum input offset voltage of ±500 µV. It includes an internal mid-supply reference voltage output and is unity-gain stable.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'E' corresponds to the industrial temperature range (-40°C to +85°C) as defined in the datasheet. Confirm the 'SN' designation matches the 8-pin SOIC package requirements. Ensure the application environment does not exceed the absolute maximum ratings regarding input voltage limits or short-circuit currents.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel amplifier with rail-to-rail performance is required within a 2.5V to 5.5V supply range. The internal mid-supply reference simplifies biasing in single-supply designs. Consider the extended temperature variant if operation above +85°C is necessary, noting potential changes in offset voltage specifications.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MCP6021/1R/2/3/4 family of high-performance CMOS operational amplifiers. The family shares core electrical characteristics but varies by channel count and package options. The MCP6021 specifically denotes the single-channel configuration available in multiple packages including SOT-23-5, PDIP, SOIC, MSOP, and TSSOP.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes within the same family include other MCP6021 variants with different suffixes indicating package type or temperature grade, such as MCP6021-I/P or MCP6021T-E/OT. Cross-family replacements require verification of pinout compatibility and electrical parameter alignment.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the MCP6021-E/SN support Chip Select functionality?

No, the Chip Select (CS) pin feature is exclusive to the MCP6023 model within this family.

What is the purpose of the VREF pin on this device?

The VREF pin provides an unbuffered internal mid-supply reference voltage, generated by a resistor divider, useful for biasing circuits in single-supply applications.
