PIN DESCRIPTIONS

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

3.1

Analog Output

The output pin (VOUT) is a low impedance voltage

source. The selected gain (G) and input voltage (VIN)

determine its value.

3.2

Analog Input

The analog inputs (VIN) are high impedance CMOS

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

inverting gains are available through these inputs.

3.3

Power Supply (VSS and VDD)

The Positive Power Supply Pin (VDD) is 1.8V to 5.5V

higher than the Negative Power Supply Pin (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 a local bypass capacitor (typically 0.01 µF to

0.1 µF) within 2 mm of the VDD pin. These parts need

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

100 mm of the VDD pin; it can be shared with nearby

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.
