3.1

Analog Outputs

The analog output pins (VOUT) are low-impedance

voltage sources.

3.2

Analog Inputs

The non-inverting 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 2.5V to 5.5V 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 that case, VSS is connected to

Ground and VDD is connected to the supply. VDD 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 VSS pin; they must be

connected 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).
