Rail-To-Rail Operational Amplifiers: MCP6231/1R/1U/2/4

Source: Microchip Technology Inc.


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 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.
