_______________General Description

Maxim’s redesigned DG408 and DG409 CMOS analog

multiplexers now feature guaranteed matching between

channels (8Ω max) and flatness over the specified sig-

nal 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/demultiplex-

er. Both muxes operate with a +5V to +30V single sup-

ply 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 stan-

dard DG408 and DG409.
