MCP6231/1R/1U/2/4  
20 µA, 300 kHz Rail-to-Rail Op Amp  
Description  
Features  
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 + 300 mV to VSS – 300 mV.  
These op amps are designed in one of Microchip’s  
advanced CMOS processes.  
• Gain Bandwidth Product: 300 kHz (typical)  
• Supply Current: IQ = 20 µA (typical)  
• Supply Voltage: 1.8V to 6.0V  
• Rail-to-Rail Input/Output  
• Extended Temperature Range: -40°C to +125°C  
• Available in 5-Pin SC70 and SOT-23 packages
