Product description
Maxim's redesigned DG417/DG418/DG419 precision,
CMOS, monolithic analog switches now feature guaranteed
on-resistance matching (3½ max) between
switches and guaranteed on-resistance flatness over
the signal range (4½ max). These switches conduct
equally well in either direction and guarantee 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 temperature
(less than 5nA at +85°C).
The DG417/DG418 are single-pole/single-throw (SPST)
switches. The DG417 is normally closed, and the
DG418 is normally open. The DG419 is singlepole/
double-throw (SPDT) with one normally closed
switch and one normally open switch. Switching times
are less than 175ns max for tON and less than 145ns
max for tOFF. Operation is from a single +10V to +30V
supply, or bipolar ±4.5V to ±20V supplies. The
improved DG417/DG418/DG419 are fabricated with a
44V silicon-gate process
