MCP6477 & MCP6479 3MHz Operational Amplifiers Microchip Technology MCP6477 and MCP6479 3MHz Operational Amplifiers come with enhanced EMI protection minimizing electromagnetic interference from external sources. This feature makes it well-suited for EMI-sensitive applications like power lines, radio stations, and mobile communications. The MCP6477 and MCP6479 amplifiers operate with a single supply voltage as low as 1.8V, while only drawing 170µA/amplifier (typical) of quiescent current. These operational amplifiers exhibit low input offset voltage (±1.6mV, maximum), rail-to-rail input and output operation, unity-gain stability, and has a gain-bandwidth product of 3MHz.
