PIN DESCRIPTIONS

Descriptions of the pins are listed in Table 3-1 (single op amps) and Table 3-2 (dual and quad op amps).

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

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

connected directly to the non-inverting input of op amp

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

packages.

3.4

CS Digital Input

This is a CMOS, Schmitt-triggered input that places the

part into a low-power mode of operation.

3.5

Typically, these parts are used in a single (positive)

need a local bypass capacitor (typically 0.01 µF to

to use a bulk capacitor (within 100 mm), which can be

shared with nearby analog parts.
