This pin-compatible, 8-/10-/12-/14bit resolution family is optimized for low power operation, while maintaining excellent dynamic performance. The AD9704/AD9705/ AD9706/AD9707 family is pin-compatible with the AD9748/AD9740/ AD9742/AD9744 family of TxDAC converters and is specifically optimized for the transmit signal path of communication systems. All of the devices share the same interface, LFCSP package, and pinout, providing an upward or downward component selection path based on performance, resolution, and cost. The AD9704/AD9705/ AD9706/AD9707 offer exceptional ac and dc performance, while supporting update r...
