AXS2005B Summary:
AXS2005B is a single channel Class AB audio power amplifier. Powered by a 5V power supply, THD+N=10%, it can output 2.4W power on a 4-ohm load.
The excellent noise and THD indicators of AXS2005B can provide high-quality audio signal amplification. A very small number of peripheral components can provide stable chip operation, greatly reducing PCB area and lowering costs.
AXS2005B has an extremely low turn off current, greatly extending the standby time of the system. The OTP protection function enhances the reliability of the system. Enabling and disabling the POP click suppression function improves the auditory perception of the system while simplifying system debugging.
AXS2005B provides SOP8 packaging.
