♦ Plug-In Upgrades for Industry-Standard

Maxim’s 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 (3Ω ma x) b e twe e n

switches and guaranteed on-resistance flatness over

the signal range (4Ω max). 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).
