60mW, DirectDrive, Stereo Headphone Amplifier  
with Low RF Susceptibility and Shutdown  
/MAX9724B  
General Description  
Features  
The MAX9724A/MAX9724B stereo headphone ampli-  
fiers are designed for portable equipment where board  
space is at a premium. These devices use a unique,  
patented† DirectDrive® architecture to produce a  
ground-referenced output from a single supply, elimi-  
nating the need for large DC-blocking capacitors, sav-  
ing cost, board space, and component height. The  
MAX9724 suppresses RF radiation received by input  
and supply traces acting as antennas and prevents the  
amplifier from demodulating the coupled noise. The  
MAX9724A offers an externally adjustable gain while  
the MAX9724B has an internally preset gain of -1.5V/V.  
The MAX9724A/MAX9724B deliver up to 60mW per  
channel into a 32Ω load and have low 0.02% THD+N.  
An 80dB at 1kHz power-supply rejection ratio (PSRR)  
allows these devices to operate from noisy digital sup-  
plies without an additional linear regulator.  
Comprehensive click-and-pop circuitry suppresses  
audible clicks and pops on startup and shutdown.  
o Improved RF Noise Rejection (Up to 67dB Over  
Typical Amplifiers)  
o No Bulky DC-Blocking Capacitors Required  
o Low-Power Shutdown Mode, < 0.1µA  
o Adjustable Gain (MAX9724A) or Fixed -1.5V/V  
Gain (MAX9724B)  
o Low 0.02% THD+N  
o High PSRR (80dB at 1kHz) Eliminates LDO  
o Integrated Click-and-Pop Suppression  
o 2.7V to 5.5V Single-Supply Operation  
o Low Quiescent Current (3.5mA)  
o Available in Space-Saving Packages  
12-Bump UCSP (1.5mm x 2mm)  
12-Pin Thin QFN (3mm x 3mm x 0.8mm)

The MAX9724A/MAX9724B operate from a single 2.7V  
to 5.5V supply, consume only 3.5mA of supply current,  
feature short-circuit and thermal-overload protection,  
and are specified over the extended -40°C to +85°C  
temperature range. The devices are available in tiny 12-  
bump UCSP™ (1.5mm x 2mm) and 12-pin thin QFN  
(3mm x 3mm x 0.8mm) packages.
