Descriptions
The device is a miniature type infrared remote control
system receiver which has been developed and designed by
utilizing the most updated IC technology. The PIN diode
and preamplifier are assembled on lead frame, the epoxy
package is designed as an IR filter. The demodulated
output signal can directly be decoded by a microprocessor.
