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°C (typical) phase margin. This family operates from a single supply voltage as low as 1.8V, while drawing 20 A (typical) quiescent current. In addition, the MCP6231/1R/1U/2/4 family supports rail-to-railinput 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.
