DescriptionPrecision CMOS Analog Switches
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.
