    Do you know a better, cheaper smaller LM386-like IC power amplifier
    bugger than these?:

    Preferably:
    * Less than e.g. 10 legs
    * Might be heat sinkable
    * Thermal protection
    * Short-circuit proof
    * Missing Current Limiter (MCL)
    ā€¢ No switch-on and off clicks "depops"
    * Low quiescent power consumption e.g. 4mA
    * Bridged output so big output capacitors are not needed
    * Wide power supply voltage e.g 2-18V
    * Widely available (for many years?)
    * DIL - or no closer legs than SOIC.

    My best guesses for now:

    TDA7056AT 5W 9mA, 4.5-18V
    http://www.digikey.dk/scripts/dksea...=1&stock=1&quantity=0&ptm=0&fid=0&pageSize=25

    TDA7052AT 1W 7mA, 4.5-18V
    http://www.digikey.dk/scripts/dksea...=1&stock=1&quantity=0&ptm=0&fid=0&pageSize=25

    TDA8541 1W 9mA, 2.2-18V
    http://www.digikey.dk/product-detail/en/TDA8541T/N1,112/568-3475-5-ND/1129428

    Old one LM386 0,5W 4mA, 4-12V or 5-18V(-4)

    TDA7052A is nice...
