1.2W, Low-EMI, Filterless,

Class D Audio Amplifier

General Description

Features

♦ Filterless Amplifier Passes FCC Radiated

The MAX9700 mono class D audio power amplifier pro-

vides class AB amplifier performance with class D effi-

ciency, conserving board space and extending battery

life. Using a class D architecture, the MAX9700 delivers

1.2W into an 8Ω load while offering efficiencies above

90%. A patented, low-EMI modulation scheme renders

the traditional class D output filter unnecessary.

Emissions Standards with 100mm of Cable

♦ Unique Spread-Spectrum Mode Offers 5dB

Emissions Improvement Over Conventional

Methods

♦ Optional External SYNC Input

♦ Simple Master-Slave Setup for Stereo Operation

♦ 94% Efficiency

The MAX9700 offers two modulation schemes: a fixed-

frequency (FFM) mode, and a spread-spectrum (SSM)

mode that reduces EMI-radiated emissions due to the

modulation frequency. Furthermore, the MAX9700 oscil-

lator can be synchronized to an external clock through

the SYNC input, allowing the switching frequency to be

user defined. The SYNC input also allows multiple

MAX9700s to be cascaded and frequency locked, mini-

mizing interference due to clock intermodulation. The

device utilizes a fully differential architecture, a full-

bridged output, and comprehensive click-and-pop sup-

pression. The gain of the MAX9700 is set internally

(MAX9700A: 6dB, MAX9700B: 12dB, MAX9700C:

15.6dB, MAX9700D: 20dB), further reducing external

component count.

♦ 1.2W into 8Ω

♦ Low 0.01% THD+N

♦ High PSRR (72dB at 217Hz)

♦ Integrated Click-and-Pop Suppression

♦ Low Quiescent Current (4mA)

♦ Low-Power Shutdown Mode (0.1µA)

♦ Short-Circuit and Thermal-Overload Protection

♦ Available in Thermally Efficient, Space-Saving

Packages

10-Pin TDFN (3mm ✕ 3mm ✕ 0.8mm)

10-Pin µMAX

12-Bump UCSP (1.5mm ✕ 2mm ✕ 0.6mm)

Ordering Information

The MAX9700 features high 72dB PSRR, a low 0.01%

THD+N, and SNR in excess of 90dB. Short-circuit and

thermal-overload protection prevent the device from

damage during a fault condition. The MAX9700 is avail-

able in 10-pin TDFN (3mm ✕ 3mm ✕ 0.8mm), 10-pin

µMAX, and 12-bump UCSP™ (1.5mm ✕ 2mm ✕ 0.6mm)

packages. The MAX9700 is specified over the extended

-40°C to +85°C temperature range.
