Improved, Dual, High-Speed Analog Switches
_______________General Description
Maxim's redesigned DG401/DG403/DG405 analog
switches now feature guaranteed low on-resistance
matching between switches (2鈩?max) and guaranteed
on-resistance flatness over the signal range (3鈩?max).
These low on-resistance switches (20鈩?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擄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. The dual, single-pole/double-throw
DG403 has two normally open and two normally closed
switches. Switching times are 150ns max for t
ON
and
100ns max for t
OFF
, with a maximum power consump-
tion of 35碌W. These devices operate from a single
+10V to +30V supply, or bipolar supplies of 鹵4.5V to
鹵20V. Maxim's improved DG401/DG403/DG405 are
fabricated with a 44V silicon-gate process.
