CMOS Octal 8-Bit D/A Converter
General Description
Maxim's MX7228 contains eight 8-bit voltage output
digital-to-analog converters (DACs) with separate
input latches and output buffers for simple micro-
processor and TTL/CMOS interfacing. The MX7228
maintains 8-bit accuracy over the full operating
temperature range without external trimming.
Internally, data transfer into the data registers is via a
common 8-bit TTL/CMOS compatible input bus.
Logic inputs), Al, and A0 control which DAC is
loaded after WR goes low.
