Device Overview

Summary

The Microchip Technology Inc. MCP6231/1R/1U/2/4 operational amplifiers (op amps) family has a 300 kHz gain bandwidth product and 65° (typical) phase margin. This family operates from a single supply voltage as low as 1.8V, while drawing 20 µA (typical) quiescent current. In addition, the MCP6231/1R/1U/2/4 family supports rail-to-rail input and output swing, with a common mode input voltage range of VDD + 300mV to VSS – 300mV. These op amps are designed in one of Microchip’s advanced CMOS processes
