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 35?), guaranteed to match within 2? between channels and to remain flat over the analog signal range (?3? 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 injection (10pC), low power consumption (35μW), and electrostatic discharge (ESD) greater than ±2000V. The 44V maximum breakdown voltage allows rail-to-rail analog signal handling capability.
