MCP6021-E/ST

Instrumentation, Op Amps, Buffer Amps Overview

The MCP6021-E/ST is a single-channel, rail-to-rail input and output operational amplifier from Microchip Technology. It operates within a power supply range of 2.5V to 5.5V and supports an industrial temperature range of -40°C to +85°C. Key electrical characteristics include a typical gain bandwidth product of 10 MHz, a slew rate of 7.0 V/µs, and low input offset voltage of ±500 µV maximum for industrial parts. The device features unity-gain stability, low noise density of 8.7 nV/√Hz at 10 kHz, and total harmonic distortion plus noise as low as 0.00053%. It is housed in an 8-lead SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the suffix 'E' indicates Extended Temperature Range availability if required, though datasheet specifies Industrial range for standard MCP6021. Confirm 'ST' denotes the 8-lead SOIC package. Ensure the specific lot date code meets project requirements. Cross-reference with Microchip's MAPS tool for current production status and alternative packages like TSSOP or MSOP if pinout compatibility allows.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when rail-to-rail I/O is necessary with a single 2.5V to 5.5V supply. It is suitable for applications requiring 10 MHz bandwidth and low distortion. Consider the MCP6021R for SOT-23-5 packaging needs. Verify that the industrial temperature range (-40°C to +85°C) meets environmental constraints. For multi-channel needs, consider the dual MCP6022 or quad MCP6024 variants.

Instrumentation, Op Amps, Buffer Amps Part Context

The MCP6021 is part of the MCP602x family of CMOS operational amplifiers fabricated on Microchip's advanced process. This family includes single, dual, and quad configurations with consistent electrical characteristics across channel counts. The series is designed for general-purpose use, offering high performance in low-voltage applications. The E/ST variant specifically refers to the industrial temperature grade in the SOIC package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible replacements within the same package include other members of the MCP602x family such as the MCP6022 (dual) or MCP6024 (quad), provided channel count differences are acceptable. Check datasheets for exact parameter matching regarding offset voltage and bandwidth when substituting with generic op-amps.
