MAX319ESA+T

P1-P3P4-P6P7-P9P10-P12
_______________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 35Ω), guaranteed to
match within 2Ω between channels and to remain flat
over the analog signal range (∆3Ω 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
Maxim’s 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.
