XS9110A General Description:
The XS9110A is a 25W, class AB/D mono audio amplifier. It is capable of delivering 25watts of continuous average power to a 4Ω BTL load with less than 10% distortion (THD) from a 14.4V DC power supply. It offers low THD+N, allowing it to achieve high-quality sound reproduction. The XS9110A device is fully protected against faults with short-circuit protection and thermal protection. Can prevent devices form being damaged during overload conditions.
The XS9110A features a low-power consumption shutdown mode.
The XS9110A contains advanced pop & click circuitry which eliminates noise which would otherwise occur during turn-on and turn-off transitions. The XS9110A can be configured by external gain-setting resistors.
The XS9110A integrates overheating protection mechanism, The XS9110A is unity-gain stable and can be configured by external gain-setting resistors.
The XS9110A can provide your USB subwoofer, radio, Sound bar, and loudspeaker perfect solution.

XS9110A Typical Application Circuit::
In most applications, the use of magnetic bead filters can meet EMC requirements. However, the switching edge of class D power amplifier changes very quickly, so it needs to be carefully considered in the process of PCB layout. For noise and electromagnetic compatibility (EMC) requirements of the system, the following suggestions are made:
1. The decoupling capacitor on the power supply should be as close to the ground pin of the power supply as possible. For different noise sources and corresponding power decoupling capacitors that interfere, patch positions should be reserved.
2. The output current loop should be as small as possible. Whether it is a filter composed of magnetic beads or inductors and capacitors, it should be as close to the output pin as possible. This part of the circuit shall be as far away from sensitive signal lines (such as audio input signal lines) and circuits as possible.
3. The ground wire and power line shall be as short as possible and the wiring shall be widened as much as possible.
4. The heat sink should be reasonably welded in the heat dissipation area of the PCB, and copper foil should be laid in the area near the chip to strengthen the heat dissipation of the chip and PCB.
