XA9220 - 20W Stereo Class-D Audio Amplifier

Download the XA9220 datasheet PDF. This datasheet also covers the XA9220-X variant, as both devices belong to the same 20w stereo class-d audio amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

The XA9220 is a high efficiency stereo class-D audio amplifier with adjustable power limit function and dynamic temperature control.

The loudspeaker driver operates from 8~26V supply voltage and analog circuit operates at 3.3V supply voltage.

Key Features

  • z Single supply voltage 8 ~ 26V for loudspeaker driver Built-in LDO output 3.3V for others z Loudspeaker power from 24V supply BTL Mode: 20W/CH into 8Ω @0.09% THD+N PBTL Mode: 40W/CH into 4Ω @0.15% THD+N z Loudspeaker power from 13V supply BTL Mode: 10W/CH into 8Ω @10% THD+N z 87% efficient Class-D operation eliminates need for heat sink z Differential inputs z Four selectable, fixed gain settings z Internal oscillator z Short-Circuit protection with auto recovery option z Under-Voltage detectio.
