AD9739A - Analog Devices

AD9739A RF Digital-to-Analog Converters

The AD9737A/AD9739A are 11-bit and 14-bit, 2.5 GSPS high performance RF DACs that are capable of synthesizing wideband signals from dc up to 3 GHz. The AD9737A/AD9739A are pin and functionally compatible with the AD9739 with the exception that the AD9737A/AD9739A do not support synchronization or RZ mode, and are specified to operate between 1.6 GSPS and 2.5.
