POWER SUPPLY BYPASSING

Layout Considerations

All power supply and reference pins of the AD8382 must be

properly bypassed to the analog ground plane for optimum

performance.

The AD8382 is a mixed-signal, high speed, high accuracy

device. In order to fully realize its specifications, it is essential to

use a properly designed printed circuit board.

All analog supply pins may be connected directly to an analog

supply plane located as close to the part as possible. A 0.1 µF

chip capacitor should be placed as close to each analog supply

pin as possible and connected directly between each analog

supply pin and the analog ground plane.

LAYOUT AND GROUNDING

The analog outputs and the digital inputs of the AD8382 are on

opposite sides of the package. Keep these sections separated to

minimize crosstalk and coupling of digital inputs into the

analog outputs.

A minimum 47 µF tantalum capacitor should be placed near the

analog supply plane and connected directly between the supply

and analog ground planes.

All signal trace lengths should be made as short and direct as

possible to prevent signal degradation due to parasitic effects.

Note that digital signals should not cross and should not be

routed near analog signals.

A minimum 10 µF tantalum capacitor should be placed near the

digital supply pin and connected directly to the analog ground

plane. A 0.1 µF chip capacitor should be connected between the

digital supply pin and the analog ground.

It is imperative to provide a solid analog ground plane under

and around the AD8382. All ground pins of the part should be

connected directly to this ground plane with no extra signal

path length. This includes DGND, AGNDBIAS, AGND5,

AGND3,4, AGND1,2, AGND0, and AGNDDAC. The return

traces for any of the signals should be routed close to the

ground pin for that section to prevent stray signals from

coupling into other ground pins.

VREFHI, VREFLO, V2, V1 REFERENCE

DISTRIBUTION

To ensure well-matched video outputs, all AD8382s must

operate from equal reference voltages.

Each reference voltage should be distributed to each AD8382

directly from the source of the reference voltage with

approximately equal trace lengths.

A 0.1 µF chip capacitor should be placed as close to each

reference input pin as possible and directly connected between

the reference input pin and the analog ground plane.
