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 3-2:

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

MCP6275’s VOUTA/VINB+ Pin

For the MCP6275 only, the output of op amp A is

connected directly to the non-inverting input of op amp

B; this is the VOUTA/VINB+ pin. This connection makes

it possible to provide a CS pin for duals in 8-pin

packages.

3.4

Chip Select Digital Input

This is a CMOS, Schmitt triggered input that places the

part into a low power mode of operation.

3.5

Power Supply Pins

The positive power supply (VDD) is 2.0V to 6.0V 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 (positive)

supply configuration. In this case, VSS is connected to

ground and VDD is connected to the supply. VDD will

need bypass capacitors.
