Plug-In Upgrades for Industry-Standard  
Maxims redesigned DG417/DG418/DG419 precision,  
CMOS, monolithic analog switches now feature guar-  
a nte e d on-re s is ta nc e ma tc hing (3ma x) b e twe e n  
switches and guaranteed on-resistance flatness over  
the signal range (4max). These switches conduct  
e q ua lly we ll in e ithe r d ire c tion a nd g ua ra nte e low  
charge injection, low power consumption, and an ESD  
tolerance of 2000V minimum per Method 3015.7. The  
new design offers low off-leakage current over temper-  
ature (less than 5nA at +85°C).
