General Description
The Microchip Technology Inc. MCP6231/1R/1U/2/4 operational amplifiers (op amps) provide wide bandwidth for the quiescent current. The MCP6231/1R/1U/2/4 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 + 300 mV to VSS - 300 mV. These op amps are designed in one of Microchip’s advanced CMOS processes.
