PIN DESCRIPTIONS
Descriptions of the pins are listed in Table 3-1.
3.1
Analog Output (VOUT)
The output pin is a low-impedance voltage source.
3.2
Power Supply Pins (VDD, VSS)
The positive power supply (VDD) is 1.4V to 6.0V higher
than the negative power supply (VSS). For normal
operation, the other pins are at voltages between VSS
and VDD.
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
Analog Inputs (VIN+, VIN-)
The non-inverting and inverting inputs are high-
impedance CMOS inputs with low bias currents.
3.4
Exposed Thermal Pad (EP)
There is an internal connection between the Exposed
Thermal Pad (EP) and the VSS 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 (
θ
JA).
