MCP6023T-E/ST

Instrumentation, Op Amps, Buffer Amps Overview

The MCP6023T-E/ST is a single-channel, rail-to-rail input and output operational amplifier from Microchip Technology. It features a typical gain bandwidth product of 10 MHz and a slew rate of 7 V/µs. The device operates on a power supply range of 2.5V to 5.5V with a typical quiescent current of 1 mA per amplifier. Key electrical characteristics include a maximum input offset voltage of ±250 µV at extended temperatures and an input bias current of 1 pA. It includes a mid-supply reference voltage (VREF) and a Chip Select (CS) pin for low-power mode control.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the ordering suffix 'T' corresponds to the reel packaging format specified by the manufacturer. Confirm the 'E' designation indicates the Extended Temperature Range (-40°C to +125°C). Ensure the '/ST' suffix matches the required 8-lead TSSOP package type for your PCB layout. Cross-reference the full part number against the official Microchip datasheet to confirm all functional specifications align with your design requirements before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel op amp with integrated power management via the CS pin is required. The MCP6023 is suitable for designs needing a built-in mid-supply reference, eliminating the need for external resistor dividers. Consider the 10 MHz bandwidth and 7 V/µs slew rate for signal conditioning tasks. Verify that the 8-lead TSSOP package fits your board space constraints and thermal requirements compared to other package options in the family.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the MCP6021/1R/2/3/4 family of rail-to-rail input/output operational amplifiers. While the MCP6021 offers a single channel with VREF, the MCP6023 adds the Chip Select functionality for power savings. The MCP6022 provides dual channels, and the MCP6024 offers four channels. All variants share similar electrical performance characteristics but differ in channel count and specific feature sets like the CS pin.

Instrumentation, Op Amps, Buffer Amps FAQ

What is the function of the Chip Select (CS) pin?

The CS pin places the amplifier into a low-power mode. When driven high, it shuts off the internal circuitry, reducing quiescent current significantly. When driven low, the amplifier returns to normal operation.

How does the VREF pin work?

The VREF pin provides an unbuffered mid-supply reference voltage generated by an internal resistor divider. It outputs approximately VDD/2 and can be used as a bias voltage for other circuit components.

Is the MCP6023 unity-gain stable?

Yes, the MCP6023 is unity-gain stable, allowing it to be used in voltage follower configurations without risk of oscillation.
