The AD9752 is a high performance 12-bit, 125 MSPS TxDAC® D/A converter. It features excellent spurious free dynamic range performance and is suitable for wideband communication transmit channel, direct IF basestations, wireless local loop, digital radio link, direct digital synthesis (DDS) instrumentation and other applications.
The AD9752 is a high‑performance, 12‑bit TxDAC® D/A converter designed for wideband communication and instrumentation applications. It offers a 125 MSPS update rate, differential current outputs ranging from 2 mA to 20 mA, and low power dissipation, making it suitable for portable and low‑power systems.
The device is supplied by a single 4.5‑5.5 V analog supply and a 2.7‑5.5 V digital supply, and provides extensive specifications including 185 mW typical power consumption, 100 kΩ output resistance, and a ±1.0 V to 1.25 V output compliance range. Detailed pin configurations, functional block diagrams, and dynamic performance data are included for designers.
