Description

SYNC
Synchronization Logic Input. When using more than one AD7723 operated from a common master clock,
SYNC allows each ADC to simultaneously sample its analog input and update its output register. A rising
edge resets the AD7723 digital filter sequencer counter to 0. When the rising edge of CLKIN senses a logic
low on SYNC, the reset state is released. Because the digital filter and sequencer are completely reset
during this action, SYNC pulses cannot be applied continuously.

DGND/DB2
Data Output Bit.
2
DGND/DB1
Data Output Bit.
3
DGND/DB0
Data Output Bit (LSB).
4
CFMT/RD
Read Logic Input. Used in conjunction with CS to read data from the parallel bus. The output data bus is enabled
when the rising edge of CLKIN senses a logic low level on RD if CS is also low. When RD is sensed high, the output
data bits, DB15 to DB0, are high impedance.
5
DGND/DRDY
Data Ready Logic Output. A falling edge indicates a new output word is available to be read from the output data
register. DRDY returns high upon completion of a read operation. If a read operation does not occur between output
updates, DRDY pulses high for two CLKIN cycles before the next output update. DRDY also indicates when
conversion results are available after a SYNC sequence.
