The AD9753 is a high performance, low power, 12-bit, 300MSPS dual channel audio DAC with excellent SFDR and IMD performance. It integrates a high quality 12-bit TxDAC+ converter that provides excellent SFDR and IMD performance. The AD9753 operates from a single 3.3V supply and consumes 155mW of power.
The AD9753 is a dual‑muxed‑port, ultrahigh‑speed 12‑bit CMOS DAC that integrates a high‑quality TxDAC+ core, on‑chip 1.20 V band‑gap reference and digital interface circuitry in a 48‑lead LQFP package. It delivers up to 300 MSPS conversion rate, supports differential or single‑ended clock inputs, and offers low‑power operation (155 mW at 3.3 V).
The datasheet provides detailed specifications, pin descriptions, dynamic performance graphs, and application guidance for communications, digital synthesis, QAM and OFDM systems. It also includes mechanical dimensions, evaluation‑board layouts, and revision history for design engineers.
