1.3W, Filterless, Stereo Class D Audio

Power Amplifier

General Description

Features

The MAX9701 stereo class D audio power amplifier pro-

vides class AB amplifier audio performance with the

benefits of class D efficiency, eliminating the need for a

heatsink while extending battery life. The MAX9701

delivers up to 1.3W per channel into an 8Ω load while

offering 87% efficiency. Maxim’s next-generation, low-

EMI modulation scheme allows the amplifier to operate

without an external LC filter while still meeting FCC EMI

emission levels.

♦ Patented Spread-Spectrum Modulation Lowers

Radiated Emissions

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

♦ 1.3W Stereo Output (8Ω, V

= 5V, THD+N = 1%)

♦ No LC Output Filter Required

♦ 87% Efficiency (R = 8Ω, P = 1000mW)

♦ Less Than 0.1% THD+N

♦ High 80dB PSRR

The MAX9701 offers two modulation schemes: a fixed-fre-

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

mode that reduces EMI-radiated emissions. The

MAX9701 oscillator can be synchronized to an external

clock through the SYNC input, allowing synchronization of

multiple Maxim class D amplifiers. The sync output

(SYNC_OUT) can be used for a master-slave application

where more channels are required. The MAX9701 fea-

tures a fully differential architecture, a full bridge-tied load

(BTL) output, and comprehensive click-and-pop suppres-

sion. The device features internally set gains of 0dB, 6dB,

12dB, and 18dB selected through two gain-select inputs,

further reducing external component count.

♦ Fully Differential Inputs

♦ Integrated Click-and-Pop Suppression

♦ Typical Low Quiescent Current (9mA)

♦ Typical Low-Power Shutdown Mode (0.1µA)

♦ Short-Circuit and Thermal-Overload Protection

♦ Available in Thermally Efficient, Space-Saving

Packages

24-Pin Thin QFN-EP (4mm x 4mm x 0.8mm)

20-Pin TSSOP

The MAX9701 features high 80dB PSRR, less than 0.1%

THD+N, and SNR in excess of 88dB. Short-circuit and

thermal-overload protection prevent the device from

being damaged during a fault condition. The MAX9701 is

available in 24-pin thin QFN-EP (4mm x 4mm x 0.8mm),

20-pin TSSOP, and 20-bump UCSP™ (2mm x 2.5mm x

0.6mm) packages. The MAX9701 is specified over the

extended -40°C to +85°C temperature range.
