MCP6291-E/MS

Instrumentation, Op Amps, Buffer Amps Overview

The MCP6291-E/MS is a single-channel operational amplifier 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 single 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, allowing operation within 300 mV of the supply rails. The component is available in an 8-lead MSOP package and functions over an extended temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'E' indicates the standard extended temperature grade (-40°C to +125°C) rather than high-temperature variants. Confirm the 'MS' designation corresponds to the 8-lead MSOP surface-mount package. Ensure compatibility with the required supply voltage range of 2.4V to 6.0V for your specific circuit design before ordering.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a general-purpose op amp requires rail-to-rail performance with moderate speed. It is suitable for designs needing low power consumption without sacrificing bandwidth. Consider alternative family members like the MCP6295 if dual channels or chip-select functionality are required within the same package footprint.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MCP6291/1R/2/3/4/5 family of CMOS operational amplifiers. The family shares common electrical characteristics but varies in channel count and package options. The MCP6291 specifically denotes the single-channel configuration, distinguishing it from dual (MCP6292) or quad (MCP6294) variants.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional replacements within the same family include other single-channel variants such as the MCP6291T-E/OT in SOT-23-5 packaging. Cross-family replacements require matching GBWP, supply voltage, and package dimensions.
