AS3527 Datasheet (austriamicrosystems AG) - Advanced Audio Processor System

AS3527, Advanced Audio Processor System

The AS3665 is a capacitive low noise charge pump with 9 current sources.

The charge pump automatically switches between 1:1 and 1:1.5 modes.

The connected current sources have a very low voltage compliance to improve efficiency of the whole system.

Three current sources have the possibility to opera
