Description
The EAIRMIA3 devices are miniature type infrared receivers
which have been developed and designed by using the latest
IC technology.
The photo diode and preamplifier are assembled onto a lead
frame and molded into an epoxy package which operates as
an IR filter.
The receiver provides a modulated output signal which can
be used for IR code learning and IR repeater.
Applications
• IR code learning
• IR repeater
• Remote control
