Precision, CMOS Analog Switches
_______________General Description
The MAX317/MAX318/MAX319 are precision, CMOS,
monolithic analog switches. The single-pole single-
throw (SPST) MAX317 is normally closed (NC), the
SPST MAX318 is normally open (NO), and the single-
pole double-throw (SPDT) MAX319 has one normally
open and one normally closed switch. All three parts
offer low on resistance (less than 35â¦), guaranteed to
match within 2⦠between channels and to remain flat
over the analog signal range (â3⦠max). They also
offer low leakage (less than 250pA at +25°C and less
than 6nA at +85°C) and fast switching (turn-on time
less than 175ns and turn-off time less than 145ns).
The MAX317/MAX318/MAX319 are fabricated with
Maximâs new improved silicon-gate process. Design
improvements guarantee extremely low charge injec-
tion (10pC), low power consumption (35µW), and elec-
trostatic discharge (ESD) greater than ±2000V. The
44V maximum breakdown voltage allows rail-to-rail ana-
log signal handling capability.
