MCP6021/2/3/4
3.0
The MCP6021/2/3/4 family of operational amplifiers
are fabricated on Microchip’s state-of-the-art CMOS
process. They are unity-gain stable and suitable for a
wide range of general-purpose applications.
3.1
The MCP6021/2/3/4 amplifier family is designed to not
exhibit phase inversion when the input pins exceed the
supply voltages. Figure 2-27 shows an input voltage
exceeding both supplies with no resulting phase
inversion.
The input stage of the MCP6021/2/3/4 family of devices
uses two differential input stages in parallel; one
operates at low common-mode input voltage (V
while the other operates at high V
the device operates with V

possible reliability problems. Thus, applications that

The MCP6023 is a single amplifier with chip select
(CS). When CS is high, the supply current is less than
10 nA (typ) and travels from the CS pin to V
amplifier output being put into a high-impedance state.
When CS is low, the amplifier is enabled. If CS is left
floating, the amplifier will not operate properly.
Figure 1-1 and Figure 2-39 show the output voltage
and supply current response to a CS pulse.

The single op amps (MCP6021 and MCP6023) have
an internal mid-supply reference voltage connected to
the V
internally tied to V
on and always provides a mid-supply reference. With
the MCP6023, taking the CS pin high conserves power
by shutting down both the op amp and the V
circuitry. Taking the CS pin low turns on the op amp and
