MCP652-E/MF

Instrumentation, Op Amps, Buffer Amps Overview

The MCP652-E/MF is a dual-channel operational amplifier from the Microchip MCP65X family, housed in an 8-lead MSOP package. It features a 50 MHz gain-bandwidth product and a 30 V/µs slew rate. The device operates on a single supply voltage ranging from +2.5V to +5.5V. Key electrical characteristics include a maximum input offset voltage of ±200 µV after calibration, a typical quiescent current of 6.0 mA per channel, and high output drive capability of ±100 mA. It supports rail-to-rail output operation with an input range that includes the negative rail.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature grade (-40°C to +125°C) and 'MF' denotes the 8-lead MSOP package. Confirm the datasheet revision matches your design requirements. Ensure the ordering part number aligns exactly with the required channel count and package style before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when dual-channel high-speed amplification is needed with minimal offset drift. The self-calibration feature makes it suitable for precision applications where initial offset must be minimized without external trimming. Consider the 6 mA quiescent current per channel against power constraints compared to lower-speed alternatives.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the MCP652 achieve low input offset voltage?

The MCP652 utilizes internal mCal (micro-calibration) technology. At power-up, or when the CAL/CS pin is toggled, the device performs an internal calibration to minimize the input offset voltage to a maximum of ±200 µV.

What is the input common-mode voltage range?

The input range includes the negative rail (VSS). The common-mode voltage can extend down to VSS - 0.3V and up to VDD - 1.3V, allowing for full rail-to-rail input compatibility in single-supply systems.
