MCP6021T-E/ST

Instrumentation, Op Amps, Buffer Amps Overview

The MCP6021T-E/ST 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 offers low noise (8.7 nV/√Hz at 10 kHz) and low total harmonic distortion (0.00053% THD+N). Extended temperature parts specify a maximum input offset voltage of ±250 µV. It includes an internal mid-supply reference voltage and is unity-gain stable.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output capability for maximum dynamic range
• Internal mid-supply voltage reference generation
• Low power consumption with typical quiescent current of 1 mA
• High performance with 10 MHz bandwidth and low noise density

Instrumentation, Op Amps, Buffer Amps Applications

• Multi-pole active filters
• Audio processing circuits
• DAC buffer stages
• Medical instrumentation signal conditioning
• Test equipment front-ends

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the package type matches the required footprint, as the 'ST' suffix indicates an 8-lead TSSOP package. Confirm the temperature grade corresponds to the application environment; the 'E' suffix denotes extended temperature operation (-40°C to +125°C), which has different offset voltage specifications compared to industrial grades. Ensure the design accounts for the unbuffered nature of the internal VREF pin if utilized.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel op amp with rail-to-rail I/O is required in a compact surface-mount package. The extended temperature rating makes it suitable for harsh environments where standard industrial parts may fail. Consider the internal VREF feature if a stable mid-supply bias is needed without external resistors. Verify that the 10 MHz bandwidth meets the signal frequency requirements for the specific gain configuration.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MCP6021/1R/2/3/4 family of high-performance, rail-to-rail input/output operational amplifiers. While other variants in the family offer dual or quad channels, or include a Chip Select pin for power saving, the MCP6021 provides a single channel. The TSSOP package variant shares electrical characteristics with PDIP and SOIC versions but differs in physical dimensions and thermal resistance.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include the MCP6021-I/ST for industrial temperature applications. For packages other than TSSOP, the MCP6021-E/SN (SOIC) or MCP6021-E/P (PDIP) are electrically equivalent options.
