MCP6231/1R/1U/2/4 20 A, 300 kHz Rail-to-Rail Op Amp Features Description The Microchip Technology Inc. MCP6231/1R/1U/2/4 Gain Bandwidth Product: 300 kHz (typical) operational amplifiers (op amps) provide wide bandwidth Supply Current: I = 20 A (typical) Q for the quiescent current. The MCP6231/1R/1U/2/4 Supply Voltage: 1.8V to 6.0V family has a 300 kHz gain bandwidth product and 65C Rail-to-Rail Input/Output (typical) phase margin. This family operates from a Extended Temperature Range: -40C to +125C single supply voltage as low as 1.8V, while drawing 20 A (typical) quiescent current. In addition, the Available in 5-Pin SC70 and SOT-23 packages MCP6231/1R/1U/2/4 family supports rail-to-rail input and output swing, with a Common-mode input voltage Applications range of V + 300 mV to V 300 mV. These op amps DD SS Automotive are designed in one of Microchips advanced CMOS processes.
