MCP6031/2/3/4  
0.9 µA, High Precision Op Amps  
Features  
Description  
• Rail-to-Rail Input and Output  
The Microchip Technology Inc. MCP6031/2/3/4 family  
of operational amplifiers (op amps) operate with a  
single supply voltage as low as 1.8V, while drawing  
ultra low quiescent current per amplifier (0.9 µA,  
typical). This family also has low input offset voltage  
(±150 µV, maximum) and rail-to-rail input and output  
operation. This combination of features supports  
battery-powered and portable applications.  
• Low Offset Voltage: ±150 µV (maximum)  
• Ultra Low Quiescent Current: 0.9 µA (typical)  
• Wide Power Supply Voltage: 1.8V to 5.5V  
• Gain Bandwidth Product: 10 kHz (typical)  
• Unity Gain Stable  
• Chip Select (CS) capability: MCP6033  
• Extended Temperature Range:  
- -40°C to +125°C  
The MCP6031/2/3/4 family is unity gain stable and has  
a gain bandwidth product of 10 kHz (typical). These  
specs make these op amps appropriate for low fre-  
quency applications, such as battery current  
monitoring and sensor conditioning.  
• No Phase Reversal  
Applications  
The MCP6031/2/3/4 family is offered in single  
(MCP6031), single with power saving Chip Select (CS)  
input (MCP6033), dual (MCP6032), and quad  
(MCP6034) configurations.
