LM1871/1872 a large-scale electric guitar without remote control transmitter / receiver ASIC. LM1871/1872 shape pin function diagram. LM1871 internal schematic. LM1872 internal block diagram. LMl871/1872 radio-controlled special chip operating voltage range is 3 ~ 9V; Transmitter chip LMl871 frequency up to 80MHz, frequencies up to 80MHz. It is optional; It contains the oscillator, the transmitter and encoder; Channels are programmable, and the RF output power is adjustable. General remote control distance up to tens of meters. If increase the supply voltage appropriately, and add one or two high-amp circuit, the remote control distance can be increased to l~2km. Here is a typical remote control transmitter / receiver circuit composed of LM1871/1872:
