General Description
The AP130 is an oversampling class-D power amplifier for stereo audio applications. It provides high power-efficiency for filterless 8-ohm load. Build-in depop, mute and gain control features simplify the applications. BTL (Bridge-Tied-Load) configuration delivers up to 1 watt into 8-ohm load per channel at 5-V supply voltage. It allows direct coupling of the power signal. Reliability is
improved through over-temperature and short circuit protections. The class-D power amplifier enables high efficiency applications for portable devices.
