______________________________________________________________________________________
Rx ADC outputs AD0–AD9 are forced to tri-state. The
Tx DAC DA0–DA9 inputs are internally pulled to OVDD,
while the Tx DAC outputs are at 0V. The wake-up time
is 6.8s to enter Rx mode, 5s to enter Tx mode, and
6.8s to enter FD mode. When the Rx ADC outputs
transition from tri-state to active, the last converted
word is placed on the digital output bus.
In standby mode, the reference is powered but all other
device functions are off. The wake-up time from stand-
by mode is 7.2s to enter Rx mode, 21.8s to enter Tx
mode, and 21.8s to enter FD mode. When the Rx ADC
outputs transition from tri-state to active, the last con-
verted word is placed on the digital output bus.
FAST and SLOW Rx and Tx Modes
The MAX19711 features FAST and SLOW modes for
switching between Rx and Tx operation. In FAST Tx
mode, the Rx ADC core is powered on but the ADC digi-
tal outputs AD0–AD9 are tri-stated. The Tx DAC digital
bus is active and the DAC core is fully operational.
