MAX361集成电路（IC）的时钟发生器PLL频率合成器规格书PDF中文资料

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.
