Product Details

The AD9748 is the 8-bit member of the new third generation family in the TxDAC product line. This new family includes the AD9744 (14-bit), AD9742 (12-bit), and AD9740 (10-bit) high-speed TxDAC converters with a maximum sampling rate of 210 MSPS.

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.

TxDAC is a registered trademark of Analog Devices.

Product Details

The AD9748 evaluation board allows for easy set up and testing of the product in the 32-lead LFCSP package. Careful attention to layout and circuit design, combined with a prototyping area, allows the user to evaluate the AD9748 easily and effectively in any application that requires high resolution, high speed conversion.

This board allows the user the flexibility to operate the AD9748 in various configurations. Possible output configurations include transformer coupled, resistor terminated, and single and differential outputs. The digital inputs are designed to be driven from various word generators, with the on-board option to add a resistor network for proper load termination. Provisions are also made to exercise the power-down feature of the AD9748 and select the clock and data modes.
