AD4C250
Dual 1 Form A Solid State Relay DESCRIPTION
The AD4C250 is a bi-directional, double-pole, single-throw, normally open multipurpose solid-state relay. It is designed to replace electromechanical relays and reed relays in special applications that call for very fast switching times. The relay consists of two integrated circuits, each driving a pair of rugged source-to-source enhancement type DMOS transistors. Each integrated circuit is optically coupled to a light emitting diode. The output MOS transistors are specially designed to exhibit extremely low output capacitance and leakage current characteristics, making this device ideal for switching high frequency signals.
