The THS8134 is a general-purpose triple high-speed D/A converter (DAC) optimized for use in video/graphics applications. The device operates from a 5-V analog supply and a 3-V to 5-V range digital supply. The THS8134 has a sampling rate up to 80 MSPS. The device consists of three 8-bit D/A converters and additional circuitry for bi-level/tri-level sync and blanking level generation in video applications. THS8134 is also well-suited in applications where multiple well-matched and synchronously operating DACs are needed; for example, I-Q modulation and direct-digital synthesis in communications equipment.
The THS8134, THS8134A and THS8134B are general‑purpose, high‑speed digital‑to‑analog converters optimized for video and graphics applications. Each device contains three 8‑bit DACs that can operate at up to 80 MSPS and provide bi‑level or tri‑level sync and blanking control signals.
The converters are supplied in a TQFP‑48 PowerPAD package, accept a 5‑V analog supply and a 3‑V to 5‑V digital supply, and include an internal 1.35 V voltage reference. They can directly drive standard 75‑Ω video loads and generate full‑scale video/sync with a 7:3 ratio compliant with SMPTE standards.
