Audio Subsystem with Mono Class D

Speaker and Class H Headphone Amplifier

General Description

Features

Sꢀ1.6V_to_2.0V_Headphone_Supply_Voltage

The MAX97000 audio subsystem combines a mono

speaker amplifier with a stereo headphone amplifier and

an analog DPST switch. The headphone and speaker

amplifiers have independent volume control and on/off

control. The four inputs are configurable as two differen-

tial inputs or four single-ended inputs.

Sꢀ40mW/Channel_Headphone_Output_(R _=_16I)

The entire subsystem is designed for maximum efficiency.

The high-efficiency 725mW 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 ground-referenced signal

that does not require output coupling capacitors.

SꢀIntegrated_Distortion_Limiter_(Speaker_Outputs)

SꢀIntegrated_DPST_Analog_Switch

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.

SꢀNo_Clicks_and_Pops

SꢀTDMA_Noise_Free

All control is performed using the 2-wire, I²C interface.

The MAX97000 operates in the extended -40NC to +85NC

temperature range, and is available in the 2mm x 2mm,

25-bump WLP package (0.4mm pitch).
