| Tasim's redesigned DG401/DG403/DG405 analog switches now
feature guaranteed low on-resistance matching between switches (2? max) and guaranteed
on-resistance flatness over the signal range (3? max).
|The dual, single-pole/double-throw DG403 has
two normally open and two normally closed switches. Switching times are 150ns max for tON
and 100ns max for tOFF, with a maximum power consump-tion of 35µW. These devices operate
from a single +10V to +30V supply, or bipolar supplies of ±4.5V to ±20V. Maxim's
improved DG401/DG403/DG405 are fabricated with a 44V silicon-gate process. These low
on-resistance switches (20? typ) conduct equally well in either direction and are
guaranteed to have low charge injection (15pC max). The new design offers lower off
leakage current over temperature (less than 5nA at +85°C).
|The DG401/DG403/DG405 are dual,
high-speed switches. The single-pole/single-throw DG401 and double-pole/single- throw
DG405 are normally open dual switches.
