GENERAL DESCRIPTION
The MP7226 contains four 8-bit voltage-output Digital-to-
Analog Converters, with BiCMOS output buffer amplifiers and
interface logic on a monolithic chip. Separate on-chip latches
are provided for each of the four D/A converters. The control
logic is speed compatible with most 8-bit microprocessors. All
digital inputs are TTL/CMOS(5V) compatible.
The MP7226 is manufactured using advanced thin film resis-
tors on a double metal BiCMOS process. The MP7226 incorpo-
rates a unique bit decoding technique yielding lower glitch,
higher speed and excellent accuracy over temperature and
time. The MP7226 maintains 8-Bit accuracy over the full operat-
ing temperature range without laser trim or external adjust-
ments.
