RT9123 Datasheet | Richiek

Description The RT9123 is a mono Class-D amplifier that features high efficiency and performance. In addition to I2C control, the RT9123 also features a "HW Control Mode" selection for the I2S/Time-Division Multiplexed (TDM) interface. This mode simplifies the amplifier driver, as it does not require I2C mands to turn on or off the device. The digital audio interface supports various formats, including I2S, left-justified, rightjustified, and 8-channel TDM formats. The remended junction temperature range is - 40C to 125C, and the ambient temperature range is - 40C to 85C. 2 Applications - Smartphones - Tablets - Personal Media Players - Portable TVs - Gaming Devices - Cameras 3 Features - Class-D Speaker AMP - 3.2W Output Power @ 4 Load, THD < 10% - 8V Output Noise - Low Shutdown Current - 50A Quiescent Current in Silence Mode - Add Dynamic Range Enhancement (DRE) to Reduce Output Noise - Spread Spectrum Frequency - Fast Turn-On Time: 1ms - Support HW Control Mode without Driver...
