MCP6241/1R/1U/2/4
3.0 PIN DESCRIPTIONS
Descriptions of the pins are listed in Table 3-1 (single op amps) and Table 3-2 (dual and quad op amps).
TABLE 3-1: PIN FUNCTION TABLE FOR SINGLE OP AMPS
TABLE 3-2: PIN FUNCTION TABLE FOR DUAL AND QUAD OP AMPS
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 (V
SS
and V
DD
)
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 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).
