Tiny, Cost-Effective, SoundWire, Class D

Amplifier

MAX98363

General Description

Benefits and Features

The MAX98363 is a tiny, low-cost, SoundWire® input

Class D mono amplifier that provides industry-leading,

Class AB audio performance with Class D efficiency. The

device features an internal tone generator, interrupt con-

trol, and selectable slew-time settings for SoundWire data

output PHY. A novel pinout allows customers to use the

cost-effective wafer-level package (WLP) with no need for

expensive in-pad vias.

● Single-Supply Operation (2.5V to 5.5V) for the

MAX98363A/B

● 3.2W Output Power into 4Ω at 5V, THD+N = 10%

● 12.3mW Quiescent Power with External DVDDIO

● MIPI SoundWire v1.2 Compliant

● Programmable Slew-Rate on SoundWire Data Output

to Help Minimize EMI

● 92% Efficiency (R = 8Ω, THD+N = 10%)

● 12.8μV

● 108.5dB Dynamic Range

● Low 0.014% THD+N at 1kHz

● Sophisticated Edge-Rate Control Enables Filterless

Class D Outputs

● 82dB PSRR at 217Hz

● Low RF Susceptibility Rejects TDMA Noise from GSM

Radios

● Class D Switching Frequency Trimmed to 5% for

Better EMI Planning

Output Noise

RMS

The MAX98363 is a SoundWire peripheral device that

supports MIPI SoundWire v1.2-compatible digital interface

for audio and control data. The digital interface is highly

flexible and supports a variety of input clock frequencies.

Also, selectable slew-time controls on the SoundWire data

output PHY help minimize EMI on a range of capacitive

bus loads. The digital interface operates on 1.8V nominal

voltage supply which can be either supplied externally, or

generated by an internal LDO.

An internal tone generator, with a variety of frequency op-

tions, supports in-factory testing or system boot-up sounds

during system power-up. An externally configurable ad-

dress pin allows up to five unique SoundWire addresses

for each device part number. The MAX98363A/B operate

with DVDDIO supplied with internal LDO and can support

up to 10 MAX98363 SoundWire peripheral devices on one

data lane. The MAX98363C/D operate with externally sup-

plied DVDDIO and support up to 10 MAX98363 Sound-

Wire peripheral devices on one data lane.

● Extensive Click-and-Pop Reduction Circuitry

● Robust Short-Circuit and Thermal Protection

● Internal Tone Generator for In-Factory Testing

● Available in Space-Saving Package: 9-Bump WLP

(1.528mm x 1.528mm, 0.4mm Pitch)

Active emissions-limiting, edge-rate limiting, and over-

shoot control circuitry greatly reduce EMI. A filterless

spread-spectrum modulation scheme eliminates the need

for output filtering found in traditional Class D devices and

reduces the component count of the solution.

The device is specified over the -40°C to +85°C tempera-

ture range.

Applications

● Notebook Computers

● Tablets

● IoT Devices

● Gaming Devices (Audio and Haptics)

● Smart Speakers

● Smartphones

● Single Li-ion Cell/5V Devices
