DirectDrive Headphone Amplifier  
with External Gain  
MAX9820  
General Description  
Features  
The MAX9820 Windows Vista®-compliant stereo head-  
phone amplifier is designed for portable equipment  
where board space is at a premium. It features Maxim’s  
patented DirectDrive® architecture to produce a  
ground-referenced output from a single supply, elimi-  
nating the large output-coupling capacitors required by  
conventional single-supply headphone amplifiers.  
o Clickless/Popless Operation  
o High RF Noise Rejection  
o Windows Vista Premium Mobile Compliant  
o 2.7V to 5.5V Single-Supply Operation  
o 95mW Output Power (32Ω, V  
= 5V)  
DD  
The MAX9820 features an undervoltage lockout that  
prevents over discharging of the battery during  
brownout conditions, click-and-pop suppression that  
eliminates audible transients on startup, a low-power  
shutdown mode, and thermal-overload and short-circuit  
protection. Additionally, the MAX9820 suppresses RF  
radiation received by input and supply traces acting as  
antennas and prevents the amplifier from demodulating  
the coupled noise.  
o Low-Current Shutdown Mode, < 1µA  
o Low 3mA (V = 3.3V) Quiescent Current  
DD  
o Space-Saving, 3mm x 3mm, 10-Pin TDFN Package  
Ordering Information  
The MAX9820 is available in a 10-pin TDFN package  
(3mm x 3mm x 0.8mm) and specified over the -40°C to  
+85°C extended temperature range.
