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 op amp output pins are low-impedance voltage

sources.

3.2

Analog Inputs

The op amp non-inverting and inverting inputs are high-

impedance CMOS inputs with low bias currents.

3.3

Chip Select Digital Input

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

part into a low power mode of operation.

3.4

Power Supply Pins

normal operation, the other pins are at voltages

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

need bypass capacitors.
