Function
21
CS
Chip Select Input. This is an active low logic input used to select the AD7708/AD7718.
CS can
be used to select the AD7708/AD7718 in systems with more than one device on the serial bus or
as a frame synchronization signal in communicating with the device.
CS can be hardwired low,
allowing the AD7708/AD7718 to be operated in 3-wire mode with SCLK, DIN, and DOUT
used to interface with the device.
22
RDY
RDY is a logic low status output from the AD7708/AD7718. RDY is low when valid data exists
in the data register for the selected channel. This output returns high on completion of a read
operation from the data register. If data is not read,
RDY will return high prior to the next update
indicating to the user that a read operation should not be initiated. The
RDY pin also returns
low following the completion of a calibration cycle.
RDY does not return high after a calibration
until the mode bits are written to enabling a new conversion or calibration.
23
DOUT
Serial data output with serial data being read from the output shift register of the ADC. The output
shift register can contain data from any of the on-chip data, calibration or control registers.
24
DIN
Serial Data Input with serial data being written to the input shift register on the AD7708/AD7718
Data in this shift register is transferred to the calibration or control registers within the ADC
depending on the selection bits of the Communications register.
25
DGND
Ground Reference Point for the Digital Circuitry.
26
DVDD
Digital Supply Voltage, 3 V or 5 V Nominal.
27
XTAL2
Output from the 32 kHz Crystal Oscillator or Resonator Inverter.
28
XTAL1
Input to the 32 kHz Crystal Oscillator or Resonator Inverter.
