Microchip Technology's MCP651, MCP652 & MCP655 (MCP65X) Operational Amplifiers

The MCP651/2/5 (MCP65X) are the world's first and only op amps to include mCal, an on-chip calibration circuit that calibrates offset voltage at power-up using an internal power on-reset detector, or based upon the state of an external pin. The result is a low initial voltage offset and a means to minimize drift over time and temperature, which are extremely important for applications involving instrumentation and sensor conditioning, because this enables extremely precise measurements. The on-board calibration circuitry within the MCP65x eliminates the need for external calibrating components and minimizes software complexity by offering a simple, single-pin hardware control of the calibration. Relative to a chopper-stabilized or auto-zeroed amplifier, mCal Technology can provide a more cost-effective solution and does not have the switching noise inherent to chopper-stabilized amplifiers. mCal Technology offers a cost-effective, easy-to-use alternative by eliminating the need for external calibration and can provide a more cost-effective solution relative to a self-correcting architecture.
