MAX361

19-0180; Rev 0; 9/93 Precision, Quad, SPST Analog Switches _______________General Description The MAX361/MAX362 are precision, quad, single-pole single-throw (SPST) analog switches. The MAX361 has four normally closed (NC) switches, and the MAX362 has four normally open (NO) switches. Both parts offer low channel on resistance (less than 85Ω), guaranteed to match within 3Ω between channels and to remain flat over the analog signal range (∆9Ω max). Both parts also offer low leakage (less than 500pA at +25°C and less than 4nA at +85°C) and fast switching (turn-on time less than 250ns and turn-off time less than 170ns). The MAX361/MAX362 are fabricated with Maxim’s new improved 44V 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. These monolithic switches operate with a single positive supply (+10V to +30V) or with split supplies (±4.5V to ±20V) while retaining CMOS-logic input compatibility and fast switching. CMOS inputs provide reduced input loading. ____________________________Features o Low On Resistance: < 45Ω Typical (85Ω Max) o Guaranteed Matched On Resistance Between Channels: < 2Ω o Guaranteed Flat On Resistance over Analog Signal Range: ∆9Ω Max o Guaranteed Charge Injection: < 10pC o Guaranteed Off-Channel Leakage: <4nA at +85°C o ESD Guaranteed > 2000V p...
