80mW, DirectDrive, Stereo Headphone  
Amplifier with Common-Mode Sense  
General Description  
Features  
ꢀ No Bulky DC-Blocking Capacitors Required  
The MAX4409 stereo headphone amplifier combines  
Maxim’s DirectDrive architecture and a common-mode  
sense input, which allows the amplifier to reject com-  
mon-mode noise. Conventional headphone amplifiers  
require a bulky DC-blocking capacitor between the  
headphone and the amplifier. DirectDrive produces a  
ground-referenced output from a single supply, elimi-  
nating the need for large DC-blocking capacitors,  
which saves cost, board space, and component height.  
The common-mode voltage sensing corrects for any  
difference between SGND of the amplifier and the  
headphone return. This feature minimizes ground-loop  
noise when the HP socket is used as a line out connec-  
tion to other grounded equipment, for example, a PC  
connected to a home hi-fi system.

ꢀ 80mW per Channel into 16Ω  
ꢀ Low 0.002% THD+N  
ꢀ High 86dB PSRR  
ꢀ Integrated Click-and-Pop Suppression  
ꢀ 1.8V to 3.6V Single-Supply Operation  
ꢀ Low Quiescent Current  
ꢀ Low-Power Shutdown Mode  
ꢀ Short-Circuit and Thermal-Overload Protection  
The MAX4409 draws only 5mA of supply current, deliv-  
ers up to 80mW per channel into a 16Ω load, and has a  
low 0.002% THD+N. A high 86dB power-supply rejec-  
tion ratio allows this device to operate from noisy digital  
supplies without additional power-supply conditioning.  
The MAX4409 includes 8kꢀ ꢁSD protection on the  
headphone outputs. Comprehensive click-and-pop cir-  
cuitry eliminates audible clicks and pops on startup  
and shutdown. A low-power shutdown mode reduces  
supply current draw to only 6µA.

Ordering Information  
The MAX4409 operates from a single 1.8ꢀ to 3.6ꢀ sup-  
ply, has short-circuit and thermal overload protection,  
and is specified over the extended -40°C to +85°C tem-  
perature range. The MAX4409 is available in tiny 20-pin  
thin QFN and 14-pin TSSOP packages.
