AD9776/AD9778/AD9779 is a dual 12-/14-/16-bit, 1 GSPS digital-to-analog converter. It features low power consumption, high performance, and multiple control functions, making it suitable for wireless infrastructure and wideband communication applications.
The AD9776/AD9778/AD9779 are dual‑channel, 12‑/14‑/16‑bit digital‑to‑analog converters capable of 1 GSPS sample rates. They feature low power consumption, high SFDR, and a novel interpolation filter that allows carrier placement anywhere in the DAC bandwidth. The devices are supplied in a 100‑lead TQFP package and support SPI programming, internal PLL clock multiplication, and auxiliary DACs for VGA and offset control.
The datasheet provides detailed specifications, functional block diagrams, pin descriptions, timing diagrams, and absolute maximum ratings. It also includes application notes for wireless infrastructure, wideband communications, and direct‑conversion transmitters.
