The AD9772AAST is a 14-bit oversampling digital-to-analog converter (DAC) from Analog Devices, designed for baseband or IF waveform reconstruction. It operates from a single 3.1 V to 3.5 V supply and supports a maximum input data rate of 160 MSPS. The device integrates a 2x interpolation filter with selectable high- or low-pass response, providing 73 dB image rejection with 0.005 dB pass-band ripple. A zero-stuffing option enhances direct IF performance.
Key electrical characteristics include a typical spurious-free dynamic range (SFDR) of 74 dBc at a 25 MHz output frequency and a power dissipation of 250 mW typical, with a power-down mode reducing consumption to 13 mW. The DAC features a 14-bit parallel interface and differential current outputs (IOUTA, IOUTB). An internal 1.2 V reference and 2x/4x clock multiplier are included.
The AD9772AAST is housed in a 48-lead LQFP package (7x7 mm) with surface mount mounting. It is suitable for communication transmit channels such as W-CDMA base stations, multicarrier base stations, direct IF synthesis, and wideband cable systems.
