ESCRIPTION
:
Maxwell Technologies’ 8408 is a monolithic quad 8-bit multi-
plying digital-to-analog CMOS converter. Each DAC has its
own reference input, feedback resistor, and onboard data
latches that feature read/write capability. The readback func-
tion serves as memory for those systems requiring self-diag-
nostics.
A common 8-bit TTL/CMOS compatible input port is used to
load data into any of the four DAC data-latches. Control lines
DS1, DS2 and A/B determine which DAC will accept data.
Data loading is similar to that of a RAMs write cycle. Data can
be read back onto the same bus with control line R/W. The
8408 is a bus compatible with most 8-bit microprocessors,
including the 6800, 8080, 8085, and Z80. The 8408 operates
on a single +5 volt supply and dissipates less than 20 mW.
The 8408 is manufactured using highly stable, thin-film resis-
tors on an advanced oxide-isolated, silicon-gate, CMOS pro-
cess. The improved latch-up resistant design eliminates the
need for external protective Schottky diodes.
