    Does the TDA2030 need negative potential?

    I agree , I meant to say that for example if you are using 12 volts the amplification will be between +6 volts

    Proximity Sensor

    If you want you can try the circuit , it does not uses an kind of programming or PLC. Its a very simple proximity sensor circuit with latch control. It is basic analog electronics however it employs the use of CD4017 decade counter for latching the proximity sense signal. Proximity Sensor...

    Does the TDA2030 need negative potential?

    For any kind of amplifier dual power supply is the first priority for any electronics engineer, however single supplies can also be employed. The basic difference is that if you apply dual supply topology then your signal gets amplified between +Vcc and -Vee. In case of single supply the...
