ADM660ARZ

The ADM660ARZ is a monolithic voltage multiplier IC from Analog Devices. It has a voltage conversion factor of 2, which means it can double input voltages up to 12V. The IC operates from a single supply voltage ranging from 1.5V to 12V and can deliver an output voltage swing up to 24V.The ADM660ARZ is designed for applications requiring a higher positive voltage than the available power supply. It is commonly used in RS-232 and RS-422 communication systems, where higher voltage levels are necessary for transmitting data over long distances.This voltage multiplier IC features built-in oscillator and regulation circuitry, minimizing the need for external components and simplifying system design. It also has built-in protection features like overvoltage and reverse-voltage protection to ensure reliable operation in rugged environments.
