The MCP6021 in the 8-pin MSOP package is only available for E-temp (Extended Temperature) parts. The MCP6021
in the 8-pin TSSOP package is only available for I-temp (Industrial Temperature) parts.
The MCP6021R is only available in the 5-pin SOT-23 package, and for E-temp (Extended Temperature) parts.
3.1
Analog Outputs
3.5
Power Supply (V
SS
and V
DD
)
The op amp output pins are low-impedance voltage
sources.
3.2
Analog Inputs
The positive power supply pin (V
DD
) is 2.5V to 5.5V
higher than the negative power supply pin (V
SS
). For
normal operation, the other pins are at voltages
between V
SS
and V
DD
.
Typically, these parts are used in a single (positive)
supply configuration. In this case, V
SS
is connected to
ground and V
DD
is connected to the supply. V
DD
will
need a local bypass capacitor (typically 0.01 µF to
0.1 µF) within 2 mm of the V
DD
pin. These parts need
to use a bulk capacitor (typically 1 µF or larger) within
100 mm of the V
DD
pin; it can be shared with nearby
analog parts.
The op amp non-inverting and inverting inputs are high-
impedance CMOS inputs with low bias currents.
3.3
V
REF
Output (MCP6021 and
MCP6023)
Mid-supply reference voltage provided by the single op
amps (except in SOT-23-5 package). This is an
unbuffered, resistor voltage divider internal to the part.
3.4
CS Digital Input
This is a CMOS, Schmitt-triggered input that places the
part into a low power mode of operation.
