MCP6031/2/3/4
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 output pins are low-impedance voltage sources.
3.2 Analog Inputs
The non-inverting and inverting inputs are high-
impedance CMOS inputs with low bias currents.
3.3 Chip Select Digital Input
This is a CMOS, Schmitt-trigerred input that places the
device into a low power mode of operation.
3.4 Power Supply Pins
The positive power supply (V
DD
) is 1.8V to 5.5V higher
than the negative power supply (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 bypass capacitors.
