The AD9740 is the 10-bit 210 MSPS member of the new third generation family in the TxDAC product line. The family is pin-compatible with the previous two generations (AD9764/AD9762/AD9760 and AD9754/AD9752/AD9750) with improved performance and lower power dissipation.
The TxDAC product line is optimized for the transmit signal path of communications systems. All of the devices, including the first two generations, share the same interface options, small outline package and pinout, providing an upward or downward component selection path based on performance, resolution and cost. The AD974x family has lower power dissipation than previous generations, making all three converters suitable for portable and low power applications.
