MCP6479T-E/SL

Instrumentation, Op Amps, Buffer Amps Overview

The MCP6479T-E/SL is a quad operational amplifier from the MCP6476/6R/6U/7/9 family, manufactured by Microchip Technology. It features rail-to-rail input and output capabilities with a typical gain bandwidth product of 3 MHz and a slew rate of 3.2 V/µs. The device operates on a supply voltage range of 1.8V to 5.5V, drawing a maximum quiescent current of 170 µA per amplifier. It includes enhanced EMI protection with an EMIRR of 90 dB at 1.8 GHz and maintains unity gain stability without phase reversal. The component is housed in a 14-lead SOIC package and supports an extended operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'T' indicates tape and reel packaging rather than tube. Confirm the '-E' designation corresponds to the industrial temperature grade (-40°C to +125°C). Ensure the datasheet revision matches the required specifications for your design. Check for AEC-Q100 Grade 1 qualification if automotive compliance is mandatory. Validate pinout compatibility with existing PCB footprints.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low power consumption alongside high EMI immunity. The quad configuration reduces board space compared to single or dual packages. Consider the 3 MHz bandwidth for general-purpose signal processing tasks. The rail-to-rail I/O simplifies interface requirements with single-supply logic. Evaluate the 170 µA quiescent current against battery life requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MCP6476/6R/6U/7/9 series of 3 MHz operational amplifiers. The 'MCP6479' variant specifically denotes the quad amplifier configuration. The 'T' suffix typically signifies tape and reel packaging for automated assembly. The 'SL' indicates the 14-lead SOIC package type. This family utilizes advanced CMOS technology for low noise and high precision.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include MCP6479-E/SL (tube packaging). Other variants like MCP6477 offer dual channels. Cross-referencing with other 3 MHz rail-to-rail op amps requires verifying pinout and electrical parameter compatibility.
