Description
DVAL/
RD
5
Read Input is a level sensitive logic input. The
RD
logic level is sensed on the rising edge of CLKIN.
This digital input can be used in conjunction with
CS
to read data from the device. 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–DB0 will be high impedance.
Data Ready Logic Output. A falling edge indicates a new output word is available to be read from out-
put data register. DRDY will return high upon completion of a read operation. If a read operation
does not occur between output updates, DRDY will pulse high for two CLKIN cycles before the next
output update. DRDY also indicates when conversion results are available after a SYNC or RESET
sequence and when completing a self-calibration.
