Description
The Microchip Technology Inc. MCP6231/2 opera-
tional amplifiers (op amps) provide wide bandwidth for
the quiescent current. The MCP6231/2 family has a
300 kHz Gain Bandwidth Product (GBWP) and 65°
(typ.) phase margin. This family operates from a single
supply voltage as low as 1.8V, while drawing 20 µA
(typ.) quiescent current. In addition, the MCP6231/2
family 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. These op amps are designed in one
of Microchip’s advanced CMOS processes.
