Ultra-Low Leakage
Monolithic CMOS Analog Multiplexers
General Description
The MAX828/MAX329 are monolithic CMOS analog rrjrgl-
tiplexers. The MAX328 is a single-ended, 1-of-8 device,
and the MAX329 IS a ddierential, 2-of-8 dewce.
Designed to orovide the lowest possible "on" and "oif"
leakages, these multtplexers Sthch signals from htgh
source impedance, prowding the mux operates into a
high Input tmpedahce op amp or A/D converter The
MAX328/MAX329 are pin-'or-pin replacements for the
popular DG508/DG509 th these aophcatiovs.
Adding V external 40k£2 reSIstor to each hput makes
the MAX328/MAX329 an excellent fauTt-tolerant ml-
plexer Low leakage (less than 1pA at 25C) ard 2.5K32
on resistance allow the circwt to sustain 110V AC faults
irdefih tely while maima mng an error of less thar‘ 40hv
'or normal signals (t.e , 1pA ttmes 40km
The MAX328/MAX329 work equally well wth a single
supply of 10V to 30V or dual supplies of tbv to :18V,
They a so oe"orm well wth unbalanced combinations of
supply voltage, such as +12V and -5N/ or +5V and -15VI
Low-power diss pation (1.9mW w'th :15V supplies) at
lows use of the rrultiplexers ( portable applications.
