Description

The Microchip Technology Inc. MCP6476/6R/6U/7/9

operational amplifier (op amp) operates with a single

supply voltage as low as 1.8V, while drawing low quies-

cent current (170 µA, maximum per amplifier). This op

amp also has low input offset voltage (±1.6 mV, maxi-

mum), and rail-to-rail input and output operation. In

addition, the MCP6476/6R/6U/7/9 is unity gain stable

and has a gain bandwidth product of 3 MHz (typical).

This combination of features supports battery-powered

and portable applications.

The MCP6476/6R/6U/7/9 has enhanced EMI protec-

tion minimizing Electromagnetic Interference from

external sources. This feature makes it well-suited for

EMI-sensitive applications, such as power lines, radio

stations and mobile communications.

This product family is offered in single (MCP6476), dual

(MCP6477) and quad (MCP6479) packages. All

devices are designed using an advanced CMOS pro-

cess and fully specified in the extended temperature

range, from -40°C to +125°C.
