PIN DESCRIPTIONS

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

determine its value.

3.2

Analog Input

inputs with low bias currents. Only three fixed, non-

inverting gains are available through these inputs.

3.3

normal operation, the other pins are at voltages

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

need a local bypass capacitor (typically 0.01 µF to

to use a bulk capacitor (typically 1.0 µF to 10 µF) within

analog parts.

3.4

Digital Inputs

The Chip Select (CS) input is a Schmitt-triggered,

CMOS logic input.

The Gain Select (GSEL) inputs are tri-level digital

inputs. They function similar to normal logic inputs at

low (G = +10) and high voltages (G = +50). The pin can

also be set to mid-supply (G = +1) by a low impedance

source, or by leaving this pin open.
