MOSA MS6864 Dual 2W Power Amplifiers with Volume Control Dual 2W Power Amplifier, I2C interface Stereo Input with Volume Control FEATURES Operation range: 2.4V ~ 6.5V Volume control range Gain: 0 to 21dB, 3dB/step Attenuation: 0 to -77.5dB, 1.25dB/step Output mode : Speaker( BTL)/Headphone(SE) BTL Output power RL=4Ω, 2W at 5V, 0.8W at 3.3V, 360mW at 2.4V RL=8Ω, 1.3W at 5V, 0.53W at 3.3V, 250mW at 2.4V SE Output power RL=32Ω, 93mW at 5V, 35mW at 3.3V, 15mW at 2.4V APPLICATIONS Multimedia system, Portable Digital Audio. Control interface : I2C Excellent Power Supply Rejection Ratio(PSRR) Flexibility power management Component less Reduce pop noise circuit Housed in TSSOP16(enhanced thermal PAD) package 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.
