Product details
Sure Electronics AA-AK32261 Stereo 2 x 150mW Class AB LM4881 DIY Headphone Amplifier Board
This compact, self-contained headphone amplifier board is built around the Texas Instruments designed LM4881 dual headphone amplifier IC. The LM4881 features high quality, Class AB output with minimal components and can operate with a wide array of power supplies from 8 to 24 VDC without the need for a heat sink.
Additional to its use as a headphone amplifier, this amplifier board may also be used as a preamplifier or a small loudspeaker power amplifier, with an output of up 150 mW per channel at 8 ohms. An exceptionally low total harmonic distortion and noise rating of 0.1% @ 150 mW into an 8 ohm load ensures clean output with lower impedance loads. Distortion and noise are even lower for high impedance headphone loads; 0.02% @ 75 mW into a 32 ohm load.
