Description

The MAX352 are precision, quad,single-pole single-throw (SPST) analog switches. The MAX351 has four normally closed (NC), and the MAX352 has four normally open (NO) switches. The MAX353 has two NO and two NC switches. 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). MAX352 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 MAX352 are fabricated with Maxim's new improved 44V silicon-gate process. Design improve-ments guarantee extremely low charge injection (10pC), low power consumption (35W), and electrostatic discharge (ESD) greater than 2000V. The 44V maximum breakdown voltage of MAX352 allows rail-to-rail analog signal handling.

These monolithic switches MAX352 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.
