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 (VDD, VSS)

The positive power supply (VDD) is 2.3V to 5.5V higher

than the negative power supply (VSS). For normal

operation, the other pins are at voltages between VSS

and VDD.

Typically, these parts are used in a single-supply

(positive) supply configuration. In this case, VSS is

connected to ground and VDD is connected to the

supply. VDD will need bypass capacitors.
