Description

Pin Number

Pin Number

10

4

Analog supply input pin. The device operating supply voltage range is +5V

potential. This pin should be bypassed to AGND with a parallel combination of a

10

μF and a 0.1 μF (ceramic) capacitor. The capacitors should be placed as

close to the supply pins of the part as possible.

11

5

AGND

Analog ground pin. This is the device's analog supply ground connection. It

should be connected through a low resistance and low inductance ground return

to the system power supply.

32 and 41

26 and 35

Digital supply input pins. The device operating supply voltage range is +5V

potential. This pin should be bypassed to DGND with a parallel combination of a

10

μF and a 0.1 μF (ceramic) capacitor. The capacitors should be placed as

close to the supply pins of the part as possible.

33 and 42

27 and 36

DGND

Digital ground pin. This is the device's digital supply ground connection. It should

be connected through a low resistance and low inductance ground return to the

system power supply.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

(1)

All voltages are measured with respect to GND, unless otherwise specified.

(2)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the

Electrical Characteristics. The specified specifications apply only for the test conditions listed. Some performance characteristics may

degrade when the device is not operated under the listed test conditions.

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and

specifications.
