ZN428E8/ZN428J8/ZN428D
8-BIT LATCHED INPUT D-A CONVERTER
AUGUST 1994
DS3007-2.1
The ZN428 is a monolithic 8-bit D-A converter with input
latches to facilitate updating from a data bus. The latch is
transparent when enable is LOW and the data is held when
enable is taken HIGH. The ZN428 also contains a 2.5V
reference the use of which is pin optional to retain flexibility.
An external fixed or varying reference may therefore be
substituted.
