MCP616/7/8/9
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 PNP inputs with low bias currents.
3.3 Chip Select Digital Input (CS)
This is a CMOS, Schmitt-triggered input that places the
MCP618 op amp into a low-power mode of operation.
3.4 Power Supply Pins (V
DD
, V
SS
)
The positive power supply (V
DD
) is 2.3V 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-supply
(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.
