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

Typically, these parts are used in a single (positive)

need bypass capacitors.

3.4

Exposed Thermal Pad (EP)

There is an internal electrical connection between the

be connected to the same potential on the Printed

Circuit Board (PCB).
