_______________General Description

Maxim’s redesigned DG417/DG418/DG419 precision,

CMOS, monolithic analog switches now feature guar-

anteed on-resistance matching (3

Ω max) between

switches and guaranteed on-resistance flatness over

the signal range (4

Ω 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 temper-

ature (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 single-

pole/double-throw (SPDT) with one normally closed

switch and one normally open switch. Switching times

supply, or bipolar ±4.5V to ±20V supplies. The

improved DG417/DG418/DG419 are fabricated with a

44V silicon-gate process.
