MCP6071/2/4
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 Power Supply Pins
The positive power supply (V
DD
) is 1.8V to 6.0V 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.
3.4 Exposed Thermal Pad (EP)
There is an internal electrical connection between the
Exposed Thermal Pad (EP) and the V
SS
pin; they must
be connected to the same potential on the Printed
Circuit Board (PCB).
