DG408, DG409 Single 8-Channel/Differential 4-Channel, CMOS Analog Multiplexers
4-Channel monolithic CMOS analog multiplexers are drop-in
replacements for the popular DG508A and DG509A series
devices. They each include an array of eight analog
switches, a TTL/CMOS compatible digital decode circuit for
channel selection, a voltage reference for logic thresholds
and an ENABLE input for device selection when several
multiplexers are present.
The DG408 and DG409 feature lower signal ON resistance
(<100Ω) and faster switch transition time (tTRANS < 250ns)
compared to the DG508A or DG509A. Charge injection has
been reduced, simplifying sample and hold applications. The
improvements in the DG408 series are made possible by
using a high-voltage silicon-gate process. An epitaxial layer
prevents the latch-up associated with older CMOS
technologies. Power supplies may be single-ended from +5V
to +34V, or split from ±5V to ±20V.
The analog switches are bilateral, equally matched for AC or
bidirectional signals. The ON resistance variation with
analog signals is quite low over a ±5V analog input range.
