DESCRIPTION

NAME

NO.

TxENABLE

TxENABLE is used in interleaved mode. The rising edge of TxENABLE synchronizes the data of

channels A and B. The first data after the rising edge of TxENABLE is treated as A data, while the next

data is treated as B data and so on. In any mode, TxENABLE being low sets DAC outputs to midscale.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating

conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
