MAX98371

Digital Input Class D Speaker Amplifier

with Dynamic Headroom Tracking

General Description

Beneﬁts and Features

● Wide Supply Range (5.5V to 18V)

The MAX98371 is a high-efficiency, mono Class D audio

amplifier featuring dynamic headroom tracking (DHT).

DHT automatically optimizes the headroom available to

the Class D amplifier as the power supply voltage var-

ies, due to sudden transients and declining battery life to

maintain a consistent listening experience. A wide 5.5V

to 18V supply range allows the device to reach 19W into

an 8Ω load.

● Dynamic Headroom Tracking Maintains a Consistent

Listening Experience

● Integrated Thermal Foldback Allows Robust

Operation in a WLP Package

● Remote Output Sensing Allows Up to 20dB THD+N

Improvement When Ferrites Are Used

● Class D Edge Rate Control Enables Filterless

Operation

● 110dB A-Weighted Dynamic Range

● Output Power at 1% THD+N:

The MAX98371’s flexible digital audio interface (DAI)

supports I S, left-justified, and TDM formats. The digital

audio interface accepts 32kHz, 44.1kHz, 48kHz, 88.2kHz,

and 96kHz sample rates with 16-/24-/32-bit data sup-

ported for all data formats. In TDM mode, the device can

support up to 16 channels of audio data. A unique clock-

ing structure eliminates the need for an external MCLK

signal that is typically needed for PCM communication.

This reduces pin count and simplifies board layout.

PVDD

Active emissions limiting with edge rate control minimizes

EMI, and eliminates the need for output filtering found in

traditional Class D devices.

● Space Saving, 30-Bump WLP Package (2.1mm x

An 8-bit PVDD supply voltage ADC enables the Dynamic

Headroom Tracking circuit. DHT optimizes audio program

peak behavior as the supply voltage varies and provides

flexible user-defined parameters.

Simpliﬁed Block Diagram

Thermal foldback protection ensures robust behavior

when the thermal limits of the device are exercised. The

circuit can be enabled to automatically reduce the output

power above a user specified temperature. This allows for

uninterrupted music playback even at high ambient tem-

peratures. Traditional thermal protection is also available

in addition to robust overcurrent protection.

DHT

All MAX98371 control is performed using a standard

2-wire, I C interface. One of sixteen slave addresses can

be selected through two, four-level address pins. The IC

is available in a 0.4mm pitch, 30-bump WLP package. It is

specified over the extended, -40°C to +85°C temperature

range.
