3.1 Analog Outputs
The analog output pins (V
OUT
) are low-impedance
voltage sources.
3.2 Analog Inputs
The non-inverting and inverting inputs (V
IN
+, V
IN
-, …)
are high-impedance CMOS inputs with low bias
currents.
3.3 Power Supply Pins
The positive power supply (V
DD
) is 2.5V to 5.5V higher
than the negative power supply (V
SS
). For normal
operation, the other pins are between V
SS
and V
DD
.
Typically, these parts are used in a single (positive)
supply configuration. In that case, V
SS
is connected to
ground and V
DD
is connected to the supply. V
DD
will
need bypass capacitors.
3.4 Chip Select Digital Input (CS)
The input (CS) is a CMOS, Schmitt-triggered input that
places the part into a Low Power mode of operation.
3.5 Exposed Thermal Pad (EP)
There is an internal connection between the exposed
thermal pad (EP) and the V
SS
pin; they must be con-
nected to the same potential on the printed circuit
board (PCB).
This pad can be connected to a PCB ground plane to
provide a larger heat sink. This improves the package
thermal resistance (
JA
).
