A complete IR receiver developed and optimized for carrier-frequency-modulated data transmission applications. The device combines small size with high sensitivity and noise suppression caused by daylight and lamps. An innovative and patented pad layout offers unique flexibility for IR receiver module assembly. The device supports standard carrier frequencies (33/ 36/37/38/40 /56 kHz) and three noise suppression regulation types (standard, lamp, noise) for high-volume remote control solutions.
