GENERAL DESCRIPTION
The AD9736, AD9735, and AD9734 are high performance, high
frequency DACs that provide sample rates of up to 1200 MSPS,
permitting multicarrier generation up to their Nyquist
frequency. The AD9736 is the 14-bit member of the family,
while the AD9735 and the AD9734 are the 12-bit and 10-bit
members, respectively. They include a serial peripheral interface
(SPI) port that provides for programming of many internal
parameters and enables readback of status registers.

(SPI) port that provides for programming of many internal
parameters and enables readback of status registers.
A reduced-specification LVDS interface is utilized to achieve
the high sample rate. The output current can be programmed
over a range of 8.66 mA to 31.66 mA. The AD973x family is
manufactured on a 0.18 μm CMOS process and operates from
1.8 V and 3.3 V supplies for a total power consumption of
380 mW in bypass mode. It is supplied in a 160-lead chip scale
ball grid array for reduced package parasitics.
