AD8C250
1 Form A
Solid State Relay
The AD8C250 is a bi-directional, single-pole, single-throw, normally open multipurpose solid-state relay. It is designed to replace
electromechanical and reed relays in special applications that call for very fast switching rates. The relay consists of an integrated circuit
that drives two special source-to-source enhancement type DMOS transistors with extremely low output capacitance and leakage current.
The IC is optically coupled to a light emitting diode which controls its switching. The design of the circuit makes it ideal for switching high
frequency signals.
