600 nA, Non-Unity Gain Rail-to-Rail Input/Output Op Amps  
Features  
Description  
• Low Quiescent Current: 600 nA/Amplifier (typ.)  
• Stable for gains of 10 V/V or higher  
The MCP6141/2/3/4 family of non-unity gain stable  
operational amplifiers (op amps) from Microchip  
Technology, Inc. operate with a single supply voltage  
as low as 1.4V, while drawing less than 1 µA (max.) of  
quiescent current per amplifier. These devices are also  
designed to support rail-to-rail input and output swing.  
The MCP6141/2/3/4 op amps have a gain bandwidth  
product of 100 kHz (typ.) and are stable for gains of  
10 V/V or higher. This specification makes these  
devices appropriate for battery-powered applications  
where higher frequency responses from the amplifier  
are required.  
• Rail-to-Rail Input: -0.3V (min.) to V + 0.3V (max.)  
DD  
• Rail-to-Rail Output:  
- V +10 mV (min.) to V -10 mV (max.)  
SS  
DD  
• Gain Bandwidth Product: 100 kHz (typ.)  
• Wide Supply Voltage Range: 1.4V to 5.5V (max.)  
• Available in Single, Dual and Quad  
• Chip Select (CS) with MCP6143  
Applications  
The MCP6141/2/3/4 family of op amps are offered in  
single (MCP6141), single with a Chip Select (CS) fea-  
ture (MCP6143), dual (MCP6142) and quad  
(MCP6144) configurations.
