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 temperatureµless 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.
