Hi Jared,

The closest replacement that we have for the AD9744 is the DAC904 (lower performance) or DAC5672A (higher performance).

The AD5445 has a SPI interface at 20MSPS, and we don't have a part that is an exact comparison. The closest I would offer is the DAC2932 with parallel CMOS interface.

Best Regards,

Dan

Hi dBrock,

For AD5445, do we have a SPI interface DAC, even with lower update rate, to replace competitor? Thanks!

Jared
