Low RF Susceptibility DirectDrive Stereo Head-  
phone Amplifier with 1.8V Compatible Shutdown  
C/MAX9724D  
General Description  
Features  
♦ Improved RF Noise Rejection (Up to 67dB Over  
The MAX9724C/MAX9724D stereo headphone ampli-  
fiers are designed for portable equipment where board  
space is at a premium. These devices use a unique,  
DirectDrive® architecture to produce a ground-refer-  
enced output from a single supply, eliminating the need  
for large DC-blocking capacitors, saving cost, board  
space, and component height. The MAX9724 sup-  
presses RF radiation received by input and supply  
traces acting as antennas and prevents the amplifier  
from demodulating the coupled noise. The MAX9724C  
offers an externally adjustable gain while the  
MAX9724D has an internally preset gain of -1.5V/V. The  
MAX9724C/MAX9724D 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 supplies  
without an additional linear regulator. Comprehensive  
click-and-pop circuitry suppresses audible clicks and  
pops on startup and shutdown.  
Typical Amplifiers)  
♦ No Bulky DC-Blocking Capacitors Required  
♦ Low-Power Shutdown Mode, < 0.1µA  
♦ Adjustable Gain (MAX9724C) or Fixed -1.5V/V  
Gain (MAX9724D)  
♦ Low 0.02% THD+N  
♦ High PSRR (80dB at 1kHz) Eliminates LDO  
♦ Integrated Click-and-Pop Suppression  
♦ 2.5V to 5.5V Single-Supply Operation  
♦ Low Quiescent Current (3.5mA)  
♦ Available in Space-Saving Packages  
12-Bump UCSP (1.5mm x 2mm)  
12-Pin Thin QFN (3mm x 3mm x 0.8mm)

GAIN (V/V) PIN-PACKAGE  
The MAX9724C/MAX9724D operate from a single 2.5V  
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.
