MCP6021/1R/2/3/4
3.0 PIN DESCRIPTIONS
Descriptions of the pins are listed in Table 3-1.
TABLE 3-1: PIN FUNCTION TABLE
3.1 Analog Outputs
The op amp output pins are low-impedance voltage
sources.
3.2 Analog Inputs
The op amp non-inverting and inverting inputs are high-
impedance CMOS inputs with low bias currents.
3.3 Reference Voltage (V
REF,
)
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 Chip Select Digital Input (CS)
This is a CMOS, Schmitt-triggered input that places the
part into a low power mode of operation.
3.5 Power Supply (V
SS
and V
DD
)
The positive power supply pin (V
DD
) is 2.5V to 6.0V
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 bypass capacitor.
