PIN DESCRIPTIONS

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

TABLE 3-1:

PIN FUNCTION TABLE

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.
