3.0 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 Output
The output pin (V
OUT
) is a low impedance voltage
source. The selected gain (G) and input voltage (V
IN
)
determine its value.
3.2 Analog Input
The analog inputs (V
IN
) are high impedance CMOS
inputs with low bias currents. Only three fixed, non-
inverting gains are available through these inputs.
3.3 Power Supply (V
SS
and V
DD
)
The Positive Power Supply Pin (V
DD
) is 1.8V to 5.5V
higher than the Negative Power Supply Pin (V
SS
). For
normal operation, the other pins are at voltages
between V
SS
and V
DD
.
Typically, these parts are used in a single (positive)
supply configuration. In this case, V
SS
is connected to
ground, and V
DD
is connected to the supply. V
DD
will
need a local bypass capacitor (typically 0.01 µF to
0.1 µF) within 2 mm of the V
DD
pin. These parts need
to use a bulk capacitor (typically 1.0 µF to 10 µF) within
100 mm of the V
DD
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.
