PIN DESCRIPTIONS

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

TABLE 3-1:

PIN FUNCTION TABLE

3.1

Analog Outputs

The analog output pins (VOUT) are low-impedance

voltage sources.

3.2

Analog Inputs

The noninverting and inverting inputs (VIN+, VIN-, …)

are high-impedance CMOS inputs with low bias

currents.

3.3

Power Supply Pins

The positive power supply (VDD) is 2.4V to 6.0V higher

than the negative power supply (VSS). For normal

operation, the other pins are 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.
