MS6864 Datasheet | MOSA

FEATURES - Operation range: 2.4V ~ 6.5V - Volume control range Gain: 0 to 21d B, 3d B/step Attenuation: 0 to -77.5d B, 1.25d B/step - Output mode : Speaker( BTL)/Headphone(SE) - BTL Output power RL=4Ω, 2W at 5V, 0.8W at 3.3V, 360m W at 2.4V RL=8Ω, 1.3W at 5V, 0.53W at 3.3V, 250m W at 2.4V - SE Output power RL=32Ω, 93m W at 5V, 35m W at 3.3V, 15m W at 2.4V APPLICATIONS Multimedia system, Portable Digital Audio. - Control interface : I2C - Excellent Power Supply Rejection Ratio(PSRR) - Flexibility power management - ponent 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 - 90m W 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, ponent less, make the MS6864 ideally suitable for use in the portable digital audio equipments.
