1.8W, Filterless, Ultra-Low EMI,

Stereo Class D Audio Power Amplifier

General Description

Features

♦ Filterless Amplifier Passes FCC-Radiation

The MAX9773 3rd-generation, ultra-low EMI, stereo,

Class D audio power amplifier provides Class AB per-

formance with Class D efficiency. The MAX9773 deliv-

ers 1.8W per channel into a 4Ω load, and offers

efficiencies above 90%. Active emissions limiting (AEL)

circuitry greatly reduces EMI by actively controlling the

output FET gate transitions under all possible transient

conditions. AEL controls high-frequency emissions

resulting from conventional Class D free-wheeling

behavior in the presence of an inductive load. Zero-

dead-time (ZDT) technology maintains state-of-the-art

efficiency and THD+N performance by allowing the out-

put FETs to switch simultaneously without cross con-

duction. A spread-spectrum modulation scheme

eliminates the need for output filtering found in tradition-

al Class D devices. These design concepts reduce

component count and extend battery life.

Emissions Standards with 6in of Cable

♦ Unique Spread-Spectrum Mode and Active

Emissions Limiting Achieves Better than 15dB

Margin Under FCC Limit

♦ Zero Dead Time (ZDT) H-Bridge Maintains Good

THD+N Performance

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

♦ Stereo Output (4Ω, V

= 5V, THD+N = 1%,

OUT

= 1.8W)

♦ No LC Output Filter Required

♦ 85% Efficiency (R = 8Ω, P = 600mW)

♦ Less Than 0.1% THD+N

♦ High 80dB PSRR

♦ Fully Differential Inputs

♦ Integrated Click-and-Pop Suppression

♦ Low-Power Shutdown Mode (0.1µA)

♦ Short-Circuit and Thermal-Overload Protection

♦ Pin-for-Pin Compatible with the MAX9701

The MAX9773 offers two modulation schemes: a fixed-

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

mode that reduces EMI-radiated emissions. The

MAX9773 oscillator can be synchronized to an external

clock through the SYNC input, allowing synchroniza-

tion 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

MAX9773 features a fully differential architecture, a full

bridge-tied load (BTL) output, and comprehensive

click-and-pop suppression. The device features inter-

nally set gains of 12dB, 15.6dB, 20dB, and 26dB

selected through two gain-select inputs, further reduc-

ing external component count.

The MAX9773 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

MAX9773 is available in 24-pin thin QFN-EP (4mm x

4mm x 0.8mm), and 20-bump UCSP™ (2mm x 2.5mm x

0.6mm) packages. The MAX9773 is specified over the

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