Microchip Technology MCP6477 and MCP6479 3MHz operational amplifiers feature enhanced EMI protection to minimize electromagnetic interference from external sources. This feature makes it ideal for emi sensitive applications such as power lines, radio stations, and mobile communications. The MCP6477 and MCP6479 amplifiers operate at a single supply voltage as low as 1.8V with only 170µa/amplifier (typical) static current. These operational amplifiers have low input bias voltage (±1.6mV, maximum), rail-to-rail input-output operation, unit-gain stability, and gain-bandwidth product of 3MHz.

     The MCP6477 and MCP6479 1MHz operational amplifier product line is offered in twin (MCP6477) and quad (MCP6479) packages. These devices are designed using an advanced CMOS process and are fully specified in the extended temperature range from -40°C to 125°C. Typical applications include smoke detectors, automobiles, battery powered systems, sensor regulation, and battery current monitoring.
