Description

8-Ch/Dual 4-Ch Hi-Performance CMOS Analog Multiplexers

Maxim's redesigned DG408 and DG409 CMOS analog multiplexers now feature guaranteed matching between channels (8 max) and flatness over the specified signal range (9 max). These low on-resistance muxes (100 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 +4.5V to +30V single supply and with ±4.5V 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 plug-in upgrades for the industry standard DG408 and DG409.
