TI THS8136PHPR

The THS8136 is a general-purpose triple high-speed digital-to-analog (D/A) converter optimized for use in video/graphics applications. The device operates from 3.3-V analog and 1.8-V digital supplies with D/A converter performance assured at sampling rates up to 180 MHz. The THS8136 consists of three 10-bit D/A converters and additional circuitry for bi-level sync and blanking level generation. The current-steering DACs have been specifically designed to produce standard video output levels when directly connected to a single-ended double-terminated 75-Ω coaxial cable. By providing a dc offset in sync insertion mode, the THS8136 can generate a bi-level sync on the AG DAC output without sacrificing DAC resolution. Support is also provided for insertion of RGB or YPbPr reference or blanking levels, irrespective of the DAC input codes. A generic DAC mode is provided for applications not requiring sync generation. All digital inputs are 1.8-V compatible. The THS8136 is a fast well-matched triple DAC with current outputs optimized for graphics and video applications without sacrificing is usefulness as a generic DAC. The DAC output stages are designed to provide direct drive of doubly-terminated 75-Ω loads (37.5 Ω). The full-scale output current of all three DACs is determined by a single resistor connecting the FSADJ pin to AVSS (GND). A 3.8-kΩ resistor is suitable for most applications requiring 700-mV output levels. Additional circuitry and digital input controls for analog sync and blank level generation are provided for both RGB and YPbPr color spaces. A generic mode of operation is provided for applications not requiring sync insertion.
