ADVANCED LINEAR DEVICES, INC. e TM EPAD ENA ® B L E D ALD114813/ALD114913 QUAD/DUAL N-CHANNEL DEPLETION MODE EPAD® PRECISION MATCHED PAIR MOSFET ARRAY VGS(th)= -1.30V GENERAL DESCRIPTION APPLICATIONS ALD114813/ALD114913 are high precision monolithic quad/dual depletion mode N-Channel MOSFETS matched at the factory using ALD’s proven EPAD CMOS technology. These devices are intended for low voltage, small signal applications. They are excellent functional replacements for normally-closed relay applications, as they are normally on (conducting) without any power applied, but could be turned off or modulated when system power supply is turned on. These MOSFETS have the unique characteristics of, when the gate is grounded, operating in the resistance mode for low drain voltage levels and in the current source mode for higher voltage levels and providing a constant drain current. These MOSFETS are designed for exceptional device electrical characteristics matching. As these ...
