AD9709AST

The AD9709AST is a dual-port, high-speed, 2-channel, 8-bit CMOS DAC from Analog Devices. It integrates two high quality 8-bit TxDAC+ cores, a voltage reference, and digital interface circuitry into a small 48-lead LQFP package. The device supports update rates up to 125 MSPS and offers exceptional AC and DC performance, including 66 dBc SFDR at 5 MHz output and 0.1% gain and offset matching. It features an on-chip 1.2V reference and can operate from a single 5V or 3.3V supply, with typical power dissipation of 380 mW at 5V and 50 mW in power-down mode. The digital interface supports dual port or interleaved data with parallel input. The AD9709 is optimized for processing I and Q data in communications applications such as base stations, digital synthesis, quadrature modulation, and 3D ultrasound. The device is surface mount in a 48-LQFP (7x7 mm) package.
