Cirrus Logic CS3511: Analog Class D amplifier has closed-loop architecture

The 10W CS3511 stereo analog-input Class D amplifier uses true spread-spectrum-switching-controller technology and a delta-sigma modulator with a patented closed-loop architecture. Features include 0.025% THD+N at 5W and 0.019% at 1W, support for single-ended or fully differential inputs, and operation from 9 or 12V. The amplifier offers built-in protection and error reporting with automatic recovery from overcurrent, thermal-overload and undervoltage conditions. Measuring 6×6 mm in a thermally enhanced QFN-32 package, the CS3511 costs $1.39 (10,000).
