Overview
The CS44130 is a high-efficiency power stage for digital Class-D amplifiers. It has been designed to be con-
figured as four half-bridge channels, two half-bridge channels and one full-bridge channel, two full-bridge
channels, or one parallel full-bridge channel.
The CS44130 integrates on-chip protection for over-current, under-voltage, and over-temperature events.
Addtionally, it integrates error reporting for these events, as well any thermal warning events. The low
R
er device package, no heat sink requirements, and smaller power supplies.
The CS44130 is ideal for digital audio systems requiring space-efficient, high quality audio, such as Digital
Televisions, MP3 Docking Stations, Mini Shelf Systems, and Desktop Speakers.
