MCP6474-E/ST

Instrumentation, Op Amps, Buffer Amps Overview

The MCP6474-E/ST is a quad operational amplifier from the MCP6471/2/4 family, manufactured using an advanced CMOS process. It features a gain bandwidth product of 2 MHz and a slew rate of 1.1 V/µs. The device operates on a single supply voltage ranging from 2.0V to 5.5V with a typical quiescent current of 100 µA per amplifier. Key electrical specifications include a maximum input offset voltage of ±1.5 mV, low input bias current (up to 350 pA at +125°C), and rail-to-rail input/output capability. It is designed for unity gain stability without phase reversal.

• Active Analog Filter

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the package type matches the required footprint, as the MCP6474 series is available in SOIC and TSSOP configurations. Confirm that the 'E' suffix corresponds to the extended industrial temperature range (-40°C to +125°C) specified in the datasheet. Ensure the ordering suffix aligns with the specific tape-and-reel or tube packaging requirements for your assembly line.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low power consumption and low input bias current are critical constraints. The 2 MHz bandwidth supports moderate-speed signal conditioning tasks. Verify that the load capacitance does not exceed stability limits without isolation resistors. Consider the rail-to-rail output swing if driving ADCs or other low-voltage interfaces directly.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MCP647x family of low-input bias current operational amplifiers. It serves as the quad-channel variant within a lineup that also includes single (MCP6471) and dual (MCP6472) channel versions. The family shares identical electrical characteristics but differs in pin count and package options, allowing designers to scale channel density while maintaining consistent performance parameters.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Microchip offers the MCP6484 and MCP6494 as higher-bandwidth alternatives within the same low-bias-current family. These substitutes provide 4 MHz and 7.5 MHz gain bandwidth products respectively, while maintaining similar quiescent current and input bias current specifications.
