Hi team,
I am looking for a high output current amplifier for my mobile phone customer. They are requiring the amp:
1. Output 300mA current on 5 ohms load;
2. The bandwidth need to be over 100mA;
3. The package need to be BGA or QFN, small enough to fit in the phone.
4. Power supply better to be <5V, lower is better.
They said they could accept the two channels paralleled solution, but not accept to add a big in serial resistor. Since the swing. Could you suggest?
