DESCRIPTION
The MS6864 is low distortion stereo power amplifier (SE/BTL) integrated volume control. It can drive 2W of
continuous average power into a dual 4Ω bridged-tied (BTL) speaker or 2 * 90mW into stereo 32Ω 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 MS6864 has good features for portable equipment, including wide voltage operation 2.4V~6.5V, low power
consumption, power management, component less, make the MS6864 ideally suitable for use in the portable digital
audio equipments.
