The AD9776/AD9778/AD9779 are dual, 12-/14-/16-bit, high dynamic range DACs that provide a sample rate of 1 GSPS, thus permitting multicarrier generation up to its Nyquist frequency. They include features optimized for direct conversion transmit applications, including complex digital modulation, and gain and offset compensation. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators such as the AD8349. A serial peripheral interface (SPI) provides for programming/readback of many internal parameters. The output current can be programmed over a range of 10 mA to 30 mA. The devices are manufactured on an advanced 0.18 m CMOS process and operate from 1.8 V and 3.3 V supplies for a total power consumption of 1.0 W. They are enclosed in 100-lead TQFP packages.
