MCP6041/2/3/4
4.0
The MCP6041/2/3/4 family of op amps is manufactured
using Microchip’s state of the art CMOS process These
op amps are unity gain stable and suitable for a wide
range of general purpose, low power applications.
See Microchip’s related MCP6141/2/3/4 family of op
amps for applications, at a gain of 10 V/V or higher,
needing greater bandwidth.

The MCP6041/2/3/4 op amps are designed to not
exhibit phase inversion when the input pins exceed the
