Typical Application
Description
The Microchip Technology Inc. MCP6291/2/3/4/5 family
of operational amplifiers (op amps) provide wide
bandwidth for the current. This family has a 10 MHz
gain bandwidth product (GBWP) and a 65° phase
margin. This family also operates from a single supply
voltage as low as 2.4V, while drawing 1 mA (typ.)
quiescent current. In addition, the MCP6291/2/3/4/5
supports rail-to-rail input and output swing, with a
common mode input voltage range of V
DD
+300mV to
V
SS
– 300 mV. This family of operational amplifiers is
designed with Microchip’s advanced CMOS process.
The MCP6295 has a chip select input (CS
) for dual op
amps in an 8-pin package. This device is manufactured
by cascading the two op amps, with the output of op
amp A being connected to the non-inverting input of op
amp B. The chip select input puts the device in a Low
Power mode.
The MCP6291/2/3/4/5 family operates in the Extended
Temperature Range of -40°C to +125°C. It also has a
power supply range of 2.4V to 5.5V.
