DESCRIPTION
The 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 4ꢁ bridgedꢀtied (BTL) speaker or 2 * 90mW into stereo 32ꢁ 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.
The MS6865 has good features for portable equipment, including wide voltage operation 2.4V ~ 6.5V, low power
consumption, power management, component less, make the MS6865 ideally suitable for use in the portable digital
audio equipments.
