be initialized to these conditions when the instru-

ment is used in normal operation. Once calibration

is ready, input the command to start conversions in

the mode you have selected via the configuration

data is ready and read conversion data.

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.
