Analog Devices AD9737A/AD9739A RF DAC Datasheet
The AD9737A and AD9739A are high‑performance 11‑bit and 14‑bit RF digital‑to‑analog converters capable of up to 2.5 GSPS conversion rates. They provide direct RF synthesis, dual‑port LVDS data interfaces, and programmable output currents, making them suitable for broadband communications, DOCSIS CMTS, military jammers, test equipment, radar, and avionics.
The datasheet includes detailed electrical specifications, pin configurations, LVDS and serial port parameters, absolute maximum ratings, and ordering information. It also outlines functional block diagrams, revision history, and thermal characteristics to aid system designers in integration and calibration.
