LM1876 integrated circuit has three working mode: stand-by, squelch, and running. The current dissipation of stand-by is just 4.2mA. The power can be supplied by both positive and negative power. The typical applied circuit is as shown in the picture. Internal circuit of LM1876 integrated circuit mainly include low-voltage protection circuit, over-power protection circuit, over-heat protection circuit, two power preamp circuits of the same function, two squelch control circuits of the same function , two stand-by control circuits of the same function , and power supply processing circuit of the same circuit and so on.
