Audio Subsystem with Mono Class D Speaker

and Class H Headphone Amplifiers

General Description

Features

Sꢀ2.7V_to_5.5V_Speaker_Supply_Voltage

The MAX97001 mono audio subsystem combines a

mono speaker amplifier with a stereo headphone ampli-

fier and an analog DPST switch. The headphone and

speaker amplifiers have independent volume control and

on/off control. The 4 inputs are configurable as 2 differ-

ential inputs or 4 single-ended inputs.

The entire subsystem is designed for maximum effi-

ciency. The high-efficiency, 700mW, Class D speaker

amplifier operates directly from the battery and con-

sumes no more than 1FA in shutdown mode. The Class

H headphone amplifier utilizes a dual-mode charge

pump to maximize efficiency while outputting a ground-

referenced 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. This allows high gain for low-level sig-

nals without compromising the quality of large signals.
