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-
48
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.
