AD9774: CLK input voltage

Question In the AD9774's datasheet, you haven't specified the CLK Input voltage range? Answer The AD9774 Clock input expects CMOS level inputs with similar specifications to the Digital Inputs.

AD9774: DAC output range and external buffer

Question I am looking for high speed 14bit DAC (0 to 30MHz) with output voltage swing (prefer adjustable)of [-0.5v to 3v]. Please also advise if AD9774 DAC can be used with load resistor greater than 50ohm in order to achieve required output swing. May be some analog driver have to be used after DAC in order to fulfill above requirements. Answer The maximum output compliance range of the AD9774 is 1.25V so there is no way to get 3V from the part. Also there is no way to get a negative voltage if you terminate the output resistor to ground. A high speed op amp like the AD8055 can be used to convert the differential current output signal of the AD9774 into a single-ended voltage output that your question implies. AD8130 may provide a convenient solution to differential-signle ended conversion as it has a high inpedance Vref input allowing you to offset the output voltage by a user-defined amount. See the AD8130 datasheet page 34 for more details.
