MCP640xx/MCP642x Operation Amplifiers


Microchip's op amps for single-supply, battery-powered applications


The Microchip Technology MCP640xx and MCP642x families of low-power, single-supply operational amplifiers offer useful new options to designers of low-power equipment. Built on Microchip’s advanced CMOS process, they offer rail-to-rail input and output operation, unity gain stability, no phase reversal, and supply voltage ranges spanning 1.8 to 5.5 V. The MCP640xx offers a gain-bandwidth product of 1 MHz with only 45 µA of quiescent current (typical) while the MCP642x family serves the most power-conscious applications, delivering a 90 kHz gain-bandwidth product with a typical quiescent current of only 4.4 µA. Both families offer extended temperature range operation and devices in single, dual, and quad packages.
