MCP6293T-E/CH

Instrumentation, Op Amps, Buffer Amps Overview

The MCP6293T-E/CH is a single-channel operational amplifier from the MCP6291/1R/2/3/4/5 family, manufactured by 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 supply voltage ranging from 2.4V to 6.0V with a typical quiescent current of 1.0 mA per amplifier. It supports rail-to-rail input and output swing, with an extended operating temperature range of -40°C to +125°C. This specific variant includes a Chip Select (CS) pin for low-power mode control and is housed in a SOT-23-6 package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Features a dedicated Chip Select (CS) digital input that enables low-power shutdown mode when driven high.
• Supports rail-to-rail input and output voltage swings, allowing operation close to both supply rails.
• Designed with advanced CMOS process technology to provide wide bandwidth and low quiescent current consumption.
• Includes Schmitt-triggered logic on the CS pin to ensure stable switching between active and low-power states.

Instrumentation, Op Amps, Buffer Amps Applications

• Automotive electronics requiring AEC-Q100 Grade 1 qualification
• Photodiode amplifier circuits
• Portable equipment and battery-powered systems
• Analog filter designs

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and 'CH' indicates the SOT-23-6 package configuration. Confirm the presence of the Chip Select (CS) functionality, which distinguishes this part from standard single op-amps like the MCP6291. Ensure compatibility with automotive Grade 1 requirements if applicable to the design specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel op-amp with integrated power-down capability is required. It is suitable for applications needing 10 MHz bandwidth and rail-to-rail performance within a 2.4V to 6.0V supply range. Consider the SOT-23-6 package constraints and the specific need for the CS pin to manage system power consumption effectively.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the MCP6291/1R/2/3/4/5 family of 1.0 mA, 10 MHz Rail-to-Rail Op Amps. While the MCP6291 is a standard single op-amp, the MCP6293 adds a Chip Select pin for power management. The family utilizes Microchip's advanced CMOS process to balance speed, power efficiency, and cost-effectiveness for general-purpose and portable applications.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes include other members of the MCP629x family such as the MCP6291 (without CS) or MCP6295 (dual with CS). Verify package compatibility and thermal characteristics when replacing with variants from different series or manufacturers offering similar GBWP and supply current specs.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the Chip Select (CS) pin affect the MCP6293T-E/CH operation?

The CS pin is a CMOS, Schmitt-triggered digital input. Driving it high places the device into a low-power mode where the amplifier shuts off, significantly reducing quiescent current. Driving it low returns the device to normal operation.

What is the input common-mode voltage range for this op-amp?

The MCP6293 supports rail-to-rail input, with a common-mode input voltage range extending from VSS – 0.3V to VDD + 0.3V, allowing signals to operate very close to the supply rails.
