Hi,
Can any one suggest a good low cost audio amplifier ..?
Details are as follows power=5 watt, gain 10 db .

regards

10dB of gain is a voltage gain of only 3.16 times. Most IC amplifiers have a voltage gain of 20 times to 100 times.
Simply use an input attenuator to reduce the input signal level so an amplifier with high gain can be used.
