MCP635T-E/MF

Instrumentation, Op Amps, Buffer Amps Overview

The MCP635T-E/MF is a dual-channel operational amplifier from the MCP631/2/3/4/5/9 family, manufactured by Microchip Technology. It features a typical gain-bandwidth product of 24 MHz and a slew rate of 10 V/µs. The device operates on a supply voltage range of +2.5V to +5.5V with a typical quiescent current of 2.5 mA per channel. It provides rail-to-rail output capability and includes two Chip Select (CS) pins for independent low-power mode control. The input common-mode voltage range extends to the negative rail, and it supports an output short-circuit current of ±70 mA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'MF' corresponds to the MSOP-10 package variant as documented in the official datasheet. Confirm that the 'E' designation indicates the extended industrial temperature range of -40°C to +125°C. Ensure the ordering code matches the dual-channel configuration with two Chip Select pins. Cross-reference the manufacturer part number against the latest Microchip documentation to confirm current production status and pinout compatibility.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel op amp requires independent channel shutdown capabilities to minimize power consumption in battery-operated devices. The inclusion of two CS pins distinguishes it from the standard dual MCP632, allowing granular control over each amplifier's active state. Consider the 24 MHz bandwidth and rail-to-rail output if signal integrity across the full supply range is critical for the application design.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the MCP63x series of high-speed, low-power CMOS operational amplifiers. The family encompasses single, dual, and quad configurations, with variants like the MCP635 specifically designed for dual-channel applications requiring separate power-down controls. These amplifiers are optimized for single-supply operation and are suitable for cost-sensitive embedded systems needing high performance without excessive power draw.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The MCP632 serves as a functional substitute if independent channel shutdown is not required. For quad-channel implementations, the MCP634 or MCP639 may be considered depending on the need for Chip Select functionality.
