XS9971General Description

The XS9971 is an audio power amplifier primarily designed for demanding applications in low-power

portable systems. It is capable of delivering 5.5 watts of continuous average power to a 2Ω BTL load with less

than 10% distortion (THD) from a 5.5VDC power supply.

The XS9971 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally

suited for mobile phone and other low voltage applications where minimal power consumption is a primary

requirement.

The XS9971 contains advanced pop & click circuitry which eliminates noise which would otherwise occur

during turn-on and turn-off transitions. The XS9971 is unity-gain stable and can be configured by external

gain-setting resistors. The XS9971 integrates overheating protection mechanism, The XS9971 is unity-gain

stable and can be configured by external gain-setting resistors.

The XS9971 can provide your USB subwoofer, radio, MP3 player, and loudspeaker perfect solution.
