LA4225 circuit diagram reference

Industrial Router Crystal 3.2*2.5mm 3225 26M (26.000MHZ) 12PF 10PPM 20PPM 30PPM

inductance

SMD aluminum electrolytic capacitor

The circuit diagram of the LA4225 is as follows. It has multiple diodes, resistors and capacitors, and has two speakers. When the circuit is working, the working power supply voltage is 18V and there is a 5-pin input. When there is no sound at all, first check if the power supply of the 5-pin is normal. Check whether the load is short-circuited. If the peripheral circuit of the 5-pin is defective, it will cause a "beep" of the communication.
