Good day,:D
I would like to made an audio amplifier for my android phone and I found some information from internet.
As the following circuit shows, it’s a simple and humble 2W mini audio amplifier circuit suitable for my phone.The IC TDA7052 is a mono output amplifier coming in a 8-lead DI package (DIP). The device is mainly designed for battery-operated portable audio circuits. The features of TDA 7052 include ,no external components needed, no switch-on or switch-off click sounds , great overall stability ,very low power consumption(quiescent current 4mA) , low THD, no heat sinks required and short-circuit proof.You can get other details from TDA7052 datasheet. In the circuit the potentiometer can be used to control the volume.Capacitor C1 and C2 are meant for filtering the supplyvoltage if a battery eliminator is used as supply source.For operations using a battery C1 and C2 are no necessary.

I want to ask that:
Is it safe to use this circuit as a amp for my android phone? How to fed the stereo? And if I use a 1w 4ohm speaker.
