Precision, Dual, High-Speed Analog Switches
__________________General Description
The MAX301/MAX303/MAX305 are precision, dual, high-
speed analog switches. The single-pole single-throw (SPST)
MAX301 and double-pole single-throw (DPST) MAX305 dual
switches are normally open (NO). The single-pole double-
throw (SPDT) MAX303 has two NO and two normally closed
(NC) poles. All three parts offer low on resistance (less than
35鈩?, guaranteed to match to within 2鈩?between channels
and to remain flat over the full analog signal range (鈭?鈩?max).
They also offer low leakage (less than 250pA at +25擄C and
less than 6nA at +85擄C) and fast switching (turn-on time less
than 150ns and turn-off time less than 100ns).
The MAX301/MAX303/MAX305 are fabricated with Maxim鈥檚
new improved silicon-gate process for high system accuracy.
Design improvements guarantee extremely low charge injec-
tion (15pC) and low power consumption (35碌W). A 44V maxi-
mum breakdown voltage allows rail-to-rail analog signal
capability.
These monolithic switches operate with a single positive sup-
ply (+10V to +30V) or with split supplies (鹵4.5V to 鹵20V) while
retaining CMOS-logic input compatibility and fast switching.
CMOS inputs provide reduced input loading.
