The high-efficiency, 700mW, Class D speaker amplifier operates directly from the battery and consumes no more than 1FA in shutdown mode. The Class H headphone amplifier utilizes a dual-mode charge pump to maximize efficiency while outputting a groundreferenced signal that does not require output coupling capacitors. The speaker amplifier incorporates a distortion limiter to automatically reduce the volume level when excessive clipping occurs.
