This series of IR receiver modules is optimized for long burst remote control systems across various environments. Featuring selectable IC settings (AGC variants), these devices offer enhanced noise immunity against sources like lamps, LCD TVs, and Wi-Fi. The integrated PIN diode and preamplifier, housed in an epoxy package with an IR filter, provide a demodulated output signal directly connectable to a microprocessor for decoding. These components are not qualified for automotive specifications.
