CS5521/22/23/24/28

1.11 PCB Layout

The CS5521/22/23/24/28 should be placed entirely

over an analog ground plane with both the AGND

and DGND pins of the device connected to the an-

alog plane. Place the analog-digital plane split im-

mediately adjacent to the digital portion of the chip.

If separate digital (VD+) and analog (VA+) sup-

plies are used, it is recommended that a diode be

placed between them (the cathode of the diode

should point to VA+). If the digital supply comes

up before the analog supply, the ADC may not start

up properly.
