NE58633  
Noise reduction class-D headphone driver amplifier  
Rev. 02 — 25 May 2009  
Product data sheet  
1. General description  
The NE58633 is a stereo, noise reduction, class-D, Bridge-Tied Load (BTL) headphone  
driver amplifier. Each channel comprises a class-D BTL headphone driver amplifier, an  
electret microphone low noise preamplifier, feedback noise reduction circuit and a music  
amplifier input.  
The NE58633 operates with a battery voltage of 0.9 V to 1.7 V. The chip employs an  
on-chip DC-to-DC boost converter and internal Vref voltage reference which is filtered and  
output to ground for noise decoupling. It features mute control and plop and click reduction  
circuitry. The gain of the microphone amplifier and filter amplifier is set using external  
resistors. Differential architecture provides increased immunity to noise.  
The NE58633 is capable of driving 800 mVrms across a 16 or 32 load and provides  
ElectroStatic Discharge (ESD) and short-circuit protection.  
It is available in the 32-pin HVQFN32 (5 mm × 5 mm × 0.85 mm) package suitable for high  
density small-scale layouts and is an ideal choice for noise reduction headphones and  
educational audio aids.  
2. Features  
I Low current consumption of 4.4 mA  
I 0.9 V to 1.7 V battery operating voltage range  
I 1 % THD+N at VO = 1 VM driving 16 with a battery voltage of 1.5 V  
I 10 % THD+N at 800 mVrms output voltage driving 16 and 32 loads with a battery  
voltage of 1.5 V  
I Output noise voltage with noise reduction circuit typically 31 mVrms for Gv(cl) = 25 dB  
I On-chip mute function  
I Plop and click reduction circuitry  
I Class-D BTL differential output configuration  
I Electret microphone noise reduction polarization amplifier with external gain  
adjustment using resistors  
I Music and filter amplifier with external gain adjustment using resistors  
I DC-to-DC converter circuitry (3 V output) with 2.5 mA (typical) load current  
I Internal voltage reference pinned out for noise decoupling  
I Available in HVQFN32 package
