The LM1872 is designed as the radio or infrared ray remote control receiving decoder circuit that can be used in the electronic toys and model cars. The internal circuit is composed of the logic unit circuit, the local oscillator, the voltage regulator, the intermediate frequency circuit, the AGC circuit, the wave detector and the synchronous circuit. Features The function is complete.The external components is few.The operating frequency is wide (50kHz-72MHz).The specialized superheterodyne type design supplies the high selectivity and sensitivity.It has good power supply noise rejection capability.It connects with the standard spare servo mechanism directly.The matching model is LM1871.
