♦ Plug-In Upgrades for Industry-Standard DG441/DG442
♦ Improved rDS(ON) Match Between Channels(4Ωmax)
Maxim’s redesigned DG441/DG442 analog switches now
fe a ture on-re s is ta nc e ma tc hing (4Ω ma x) b e twe e n
switches and guaranteed on-resistance flatness over the
signal range (9Ω max). These low on-resistance switches
conduct equally well in either direction. They guarantee
low charge injection (10pC max), low power consumption
(1.65mW), and an ESD tolerance of 2000V minimum per
Method 3015.7. The new design offers lower off-leakage
current over temperature (less than 5nA at +85°C).

The DG441/DG442 are quad, single-pole/single-throw
(SPST) analog switches. The DG441 has four normally
closed switches, and the DG442 has four normally open
