Power Supply (V and V
)
DD
SS
The output pins are low-impedance voltage sources.
The positive power supply pin (VDD) is 1.4V to 5.5V
higher than the negative power supply pin (VSS). For
normal operation, the other pins are at voltages

Analog Inputs
between VSS and VDD
.
The non-inverting and inverting inputs are high-imped-
ance CMOS inputs with low bias currents.
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 can share a
bulk capacitor with nearby analog parts (within
100 mm), but it is not required.
3.3
CS Digital Input
This is a CMOS, Schmitt-triggered input that places the
part into a low-power mode of operation.
