MS6865 is low distortion stereo power amplifier that has 3 stereo inputs
with volume control. It can drive 2W of continuous average power into
a dual 4£[ bridged-tied (BTL) speaker or 2 * 90mW into stereo 32£[ single
ended (SE) headphone. The volume control offers wide range of gain and
attenuation for stereo input. All of the functions are easy setting that
can be set by I2C interface. |
