The AD9726 is a 16-bit, 400 MSPS D/A converter with excellent dynamic performance, precise linearity, and low noise.
The AD9726 is a 16‑bit DAC capable of conversion rates up to 400 MSPS. It uses LVDS inputs with internal 100 Ω terminations and provides both single‑ended and differential current outputs. An internal precision reference is included, and the device supports both single‑data‑rate and double‑data‑rate operation.
The datasheet details electrical specifications, pin configurations, timing diagrams and absolute maximum ratings. It also lists typical applications such as instrumentation, test equipment, waveform synthesis and communications systems.
