The MS6864 is low distortion stereo power amplifier (SE/BTL) integrated
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. 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. |
