19-4725; Rev 4; 9/08
Improved, 8-Channel/Dual 4-Channel,
CMOS Analog Multiplexers
Maxim’s redesigned DG408 and DG409 CMOS analog
multiplexers now feature guaranteed matching between
channels (8Ω max) and flatness over the specified signal range (9Ω max). These low on-resistance muxes
(100Ω max) conduct equally well in either direction and
feature guaranteed low charge injection (15pC max). In
addition, these new muxes offer low input off-leakage
current over temperature—less than 5nA at +85°C.
The DG408 is a 1-of-8 multiplexer/demultiplexer and
the DG409 is a dual 4-channel multiplexer/demultiplexer. Both muxes operate with a +5V to +30V single supply and with ±5V to ±20V dual supplies. ESD protection
is guaranteed to be greater than 2000V per Method
3015.7 of MIL-STD-883. These improved muxes are
pin-compatible plug-in upgrades for the industry standard DG408 and DG409.
