bandwidth for the current. This family has a 10 MHz
Supply Voltage: 2.4V to 5.5V
gain bandwidth product (GBWP) and a 65 phase
Rail-to-Rail Input/Output
margin. This family also operates from a single supply
Extended Temperature Range: -40C to +125C
voltage as low as 2.4V, while drawing 1mA (typ.)

quiescent current. In addition, the MCP6291/2/3/4/5
Single with Chip Select (CS ) (MCP6293) supports rail-to-rail input and output swing, with a
common mode input voltage range of V +300 mV to
DD
Dual with Chip Select (CS ) (MCP6295)
V 300 mV. This family of operational amplifiers is
SS
designed with Microchips advanced CMOS process.
Applications
The MCP6295 has a chip select input (CS) for dual op
Automotive
amps in an 8-pin package. This device is manufactured
Portable Equipment
by cascading the two op amps, with the output of op
Photo Diode Pre-amps
amp A being connected to the non-inverting input of op
Analog Filters amp B. The chip select input puts the device in a Low
Power mode.
Notebooks and PDAs
Battery-Powered Systems
The MCP6291/2/3/4/5 family operates in the Extended
Temperature Range of -40C to +125C. It also has a
