PIN DESCRIPTIONS

Descriptions of the pins are listed in Table 3-1.

TABLE 3-1:

PIN FUNCTION TABLE

3.1

Analog Outputs

The output pins are low-impedance voltage sources.

3.2

Analog Inputs

The non-inverting and inverting inputs are high-

impedance CMOS inputs with low bias currents.

3.3

Power Supply Pins

The positive power supply (VDD) is 1.8V 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.

3.4

Exposed Thermal Pad (EP)

There is an internal electrical connection between the

Exposed Thermal Pad (EP) and the VSS pin; they must

be connected to the same potential on the Printed

Circuit Board (PCB).
