_______________General Description

The MAX5018 is a monolithic, 8-bit digital-to-analog
converter (DAC) capable of accepting video data at
165Msps or 275Msps. Complete with video controls
(sync, blank, reference white (force high), and bright),
the MAX5018 directly drives doubly terminated 50Ω or
75Ω loads to standard composite video levels.
Standard setup level is 7.5IRE. The MAX5018 is pin
compatible with the HDAC10180 and the TDC1018,
with improved performance. The MAX5018 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

TEST-LEVEL CODES

All electrical characteristics are subject to
the following conditions:

All parameters having min/max specifica­tions are guaranteed. The Test Level column
indicates the specific device testing actually
performed during production and Quality
Assurance inspection. Any blank section in
the data column indicates that the specifica­tion is not tested at the specified condition.

Unless otherwise noted, all tests are pulsed
tests; therefore, T

j

= TC= TA.
