Description
The Microchip Technology Inc. MCP6L71/1R/2/4 family
of operational amplifiers (op amps) supports general
purpose applications. The combination of rail-to-rail
input and output, low quiescent current and bandwidth
fit into many applicaitons.
This family has a 2 MHz Gain Bandwidth Product
(GBWP) and a low 150 µA per amplifier quiescent cur-
rent. These op amps operate on supply voltages
between 2.0V and 6.0V, with rail-to-rail input and output
swing. They are available in the extended temperature
range.

The circuit used for most DC and AC tests is shown in
Figure 1-1.
This circuit can independently set V

Equation 1-1.
Note that V

is not the
circuit’s common mode voltage ((V

plus the effects (on the input offset
error, V
