Descriptions of the pins are listed in
TABLE 3-1:
3.1
The output pin (V
source. The selected gain (G) and input voltage (V
determine its value.
3.2
The analog inputs (V
inputs with low bias currents. Only three fixed, non-
inverting gains are available through these inputs.
3.3
The Positive Power Supply Pin (V
higher than the Negative Power Supply Pin (V
normal operation, the other pins are at voltages
between V
Typically, these parts are used in a single (positive)
supply configuration. In this case, V
ground, and V
need a local bypass capacitor (typically 0.01 µF to
0.1 µF) within 2 mm of the V
to use a bulk capacitor (typically 1.0 µF to 10 µF) within
100 mm of the V
analog parts.

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.
