MAX5018 is a 8-bit digital to analog converter from Texas Instruments, which can accept video data at 165Msps or 275Msps. It has complete video controls (sync, blank, reference white (force high), and bright), and can directly drive doubly terminated 50Ω or 75Ω loads to standard composite video levels. Standard setup level is 7.5IRE. MAX5018 is pin compatible with the HDAC10180 and the TDC1018, with improved performance. The product contains data and control input registers, video control logic, reference buffer, and current switches. Two performance grades of the MAX5018 are available. Both are packaged in a 24-pin PDIP in the -20°C to +85°C industrial temperature range.
The MAX5018 is a monolithic 8‑bit digital‑to‑analog converter (DAC) designed for high‑speed video applications. It supports conversion rates of 275 Msps (MAX5018A) or 165 Msps (MAX5018B) and provides complete video controls (sync, blank, bright, reference white) while driving 50 Ω or 75 Ω loads to standard composite video levels.
The device is supplied in a 24‑pin PDIP package, operates from a single –5.2 V supply, and includes differential current outputs, ESD‑protected inputs, and an external compensation pin for reference buffer tuning. Detailed electrical characteristics, pin descriptions, and application guidelines are provided for designers.
