MCP6281/2/3/4/5  
450 µA, 5 MHz Rail-to-Rail Op Amp  
Features  
Description  
• Gain Bandwidth Product: 5 MHz (typ.)  
• Supply Current: IQ = 450 µA (typ.)  
• Supply Voltage: 2.2V to 5.5V  
The Microchip Technology Inc. MCP6281/2/3/4/5  
family of operational amplifiers (op amps) provide wide  
bandwidth for the current. This family has a 5 MHz  
Gain Bandwidth Product (GBWP) and a 65° phase  
margin. This family also operates from a single supply  
voltage as low as 2.2V, while drawing 450 µA (typ.)  
quiescent current. Additionally, the MCP6281/2/3/4/5  
supports rail-to-rail input and output swing, with a  
common mode input voltage range of VDD + 300 mV to  
• Rail-to-Rail Input/Output  
• Extended Temperature Range: -40°C to +125°C  
• Available in Single, Dual and Quad Packages  
• Single with Chip Select (CS) (MCP6283)  
• Dual with Chip Select (CS) (MCP6285)  
VSS – 300 mV. This family of operational amplifiers is  
designed with Microchip’s advanced CMOS process.  
Applications  
The MCP6285 has a Chip Select (CS) input for dual op  
amps in an 8-pin package. This device is manufactured  
by cascading the two op amps (the output of op amp A  
connected to the non-inverting input of op amp B). The  
CS input puts the device in Low-power mode.  
• Automotive  
• Portable Equipment  
• Photodiode Amplifier  
• Analog Filters  
• Notebooks and PDAs  
• Battery-Powered Systems  
The MCP6281/2/3/4/5 family operates over the  
Extended Temperature Range of -40°C to +125°C. It  
also has a power supply range of 2.2V to 5.5V.
