++ + MCP6231/1R/1U/2/4 20 A, 300 kHz Rail-to-Rail Op Amp Features Description Gain Bandwidth Product: 300 kHz (typical) The Microchip Technology Inc. MCP6231/1R/1U/2/4 operational amplifiers (op amps) provide wide Supply Current: I = 20 A (typical) Q bandwidth for the quiescent current. The MCP6231/1R/ Supply Voltage: 1.8V to 6.0V 1U/2/4 family has a 300 kHz gain bandwidth product Rail-to-Rail Input/Output and 65C (typical) phase margin. This family operates Extended Temperature Range: -40C to +125C from a single supply voltage as low as 1.8V, while Available in 5-Pin SC-70 and SOT-23 packages drawing 20 A (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 Applications voltage range of V +300mV to V 300mV.
