1 General Description
The AS3658 is highly integrated power and audio
management unit. The AS3658 is designed to include
sophisticated audio features like high performance
audio DAC and ADC. It has several analog and digital
audio interface which are explained in detail in the
following sections. The AS3658 is an integrated solution
for power supply generation and monitoring, battery
management including charging.
