MAX98360A/B/C/D

Tiny, Cost-Effective, Plug-and-Play

Digital Class-D Amplifier

General Description

Benefits and Features

The MAX98360A/B/C/D is an easy-to-use, low-cost, digital

pulse-code modulation (PCM) input Class-D amplifier that

provides industry-leading, Class-AB audio performance

with Class-D efficiency. The digital audio interface au-

tomatically recognizes different PCM and TDM clocking

● Simple Plug-and-Play Design

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

● 3.2W Output Power into 4Ω at 5V

● 2.2mA Quiescent Current

● 1ms Turn-On Time (for MAX98360A and

MAX98360B)

schemes which eliminates the need for I C programming.

Simply supply power, LRCLK, BCLK, and digital audio to

generate audio. Furthermore, a novel pinout allows cus-

tomers to use the cost-effective WLP package with no

need for expensive vias.

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

● 10μV

Output Noise

RMS

● 110dB Dynamic Range

● Low 0.009% THD+N at 1kHz

● No MCLK Required

● Sample Rates of 8kHz to 96kHz

● Supports Left, Right, or (Left/2 + Right/2) Output in I S

and Left-Justified Modes

● Sophisticated Edge Rate Control Enables Filterless

Class-D Outputs

● 81dB PSRR at 217Hz

● 1.5μA Standby Current Allows Elimination of GPIO for

EN Pin

● Low RF Susceptibility Rejects TDMA Noise from GSM

Radios

The digital audio interface is highly flexible. The devices

support I S, left-justified, and 8-channel time division mul-

tiplexed (TDM) data formats. The digital audio interface

accepts 8kHz, 16kHz, 32kHz, 44.1kHz, 48kHz, 88.2kHz,

and 96kHz sample rates. Data words can be 16-bit, 24-bit,

or 32-bit in I S and left-justified modes and 16-bit or 32-bit

in TDM mode.

Digital audio interface input thresholds are ideal for inter-

facing to 1.2V and 1.8V logic. The devices can tolerate

logic input voltages up to 5.5V.

The MAX98360A and MAX98360B have fast 1ms turn-on

times while the MAX98360C and MAX98360D ramp the

volume over 13ms during turn-on and turn-off.

● Class-D Switching Frequency Trimmed to 5% for

Better EMI Planning

● Extensive Click-and-Pop Reduction Circuitry

● Robust Short-Circuit and Thermal Protection

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

(0.4mm Pitch)

The devices eliminate the need for the external MCLK sig-

nal that is typically used for PCM communication. This re-

duces EMI and possible board coupling issues in addition

to reducing the size and pin count. The devices also fea-

ture a very high wideband jitter tolerance (12ns, typ) on

BCLK and LRCLK to provide robust operation.

● 3.69mm Solution Size for WLP With A Single Bypass

Capacitor

Ordering Information appears at end of data sheet.

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.
