Description
The Microchip Technology Inc. MCP6271/2/3/4 family
of operational amplifiers (op amps) provide wide band-
width for the current. This family has a 2 MHz gain
bandwidth product and 65 phase margin. This family
also operates from a single supply voltage as low as
2.0V, while drawing 170 A (typ.) quiescent current.
Additionally, the MCP6271/2/3/4 supports rail-to-rail
input and output swing, with a common mode input
voltage range of V
DD
+ 300 mV to V
SS
- 300 mV. This
family of operational amplifiers is designed with
Microchip's advanced CMOS process.
The MCP6271/2/3/4 family operates in the Extended
Temperature Range of -40C to +125C. It also has a
power supply range of 2.0V to 5.5V.
