CMOS, Octal, 8-Bit DAC
2hlAlst'll 1i)d LAM]
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/V, Al, and A0 control which DAC is
loaded after WR goes low.
Features
. Buffered Voltage Output
. pP Compatible
. TTL/CMOS Logic Compatible
. Requires No External Adjustments
. 24-Pin Narrow DIP Package
. Operates from Single or Dual Supplies
