General Description

Maxim’s redesigned DG406 and DG407 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 DG406 is a 1 of 16 multiplexer/demultiplexer and the DG407 is a dual 8-channel multiplexer/demultiplexer. Both muxes operate with a +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 pin-compatible plug-in upgrades for the industry standard DG406 and DG407.
