ALC1003
3W Mono Class-D Audio Amplifier
 
General Description

The ALC1003 is a mono Class-D audio amplifier with a typical 4 speaker impedance, a 5V power supply, and maximum output power of 3W. The ALC1003 provides configurable input to output gain ratio, with no external components required.

For input signals, the system designer can easily choose 11dB, 14dB, 19dB, or 25dB boost gain by pulling high/low two control pins. With Class-D amplifier technology, the ALC1003 offers good audio quality, high power-efficiency, and requires fewer external components. With analog input support, the ALC1003 can also be used as a Class-AB amplifier.

The ALC1003 can output power directly to the speaker, with less power dissipation inside the silicon. This high efficiency with less run-time power consumption can extend the battery life for portable consumer electronic devices and Notebook PCs.
