Power Supply Pins
The output pins are low-impedance voltage sources.
The positive power supply (VDD) is 1.8V to 5.5V higher
than the negative power supply (VSS). For normal
operation, the other pins are at voltages between VSS
3.2
Analog Inputs
and VDD
.
The non-inverting and inverting inputs are high-
impedance 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 bypass capacitors.
3.3
Chip Select Digital Input
This is a CMOS, Schmitt-trigerred input that places the
device into a low power mode of operation.
