DESCRIPTION

The MS6336 is a 16Nbits voltageNoutput DigitalNtoNAnalog Converter (DAC) integrated class AB stereo headphone driver and stereo speaker power amplifier. It can drive 1.6W of continuous average power into a dual 4Ω bridgedNtied (BTL) speaker or 2 * 46mW into stereo 32Ω single ended (SE) headphone. The 16Nbit DAC supports popular formats as I2S, Right Justified, and Left Justified. All of the functions are set by I2C interface. The MS6336 has good features for portable equipment, including wide voltage operation 2.4V~5.5V, low power consumption, flexible power management, component less and small package TSSOP16, make the MS6336 ideally suitable for use in the portable digital audio equipments.

APPLICATION INFORMATION

A base application circuit Output mode operation -- SE mode and BTL mode The output has two modes, SE mode and BTL mode. The mode is selected by I2C code via MCU. In BTL mode, the outputs of A1(B1) and A2(B2) are then used to drive the speakers(4 Ω/8 Ω). OUTR+ OUTR- OUTL+ OUTL- SCL SDA I2 C Interface RL 4Ω / 8 Ω RL 4Ω / 8 Ω In the SE mode, the amplifiers A2 and B2 are shutdown, and become the high output impedance states. OUTR- OUTL- SCL SDA I2 C Interface RL 16Ω / 32Ω 100uF Headphone Jack Shutdown Shutdown 100uF

16-bit Audio DAC integrated Dual 1.6W Power Amplifiers REV1.0 14 www.mosanalog.com Headphone sense The output mode is SE or BTL that is decided by a h eadphone. It has to be set SE mode when a headphone is plugNin status. The output mode is selected by I2C command code by MCU. Please note that the MS6336 don’t dete ct a headphone automatically. Thus a detect function is executed via MCU.

Label 6: LED Indicator The LEDs indicate the chip status and IR received status. It keeps on a light state when the MS6336 is active. The other hand, keeps on a dark state when the MS6836 is powe rNoff. It is redNdark blink once when the MCU has received the function code correctly. SE mode and BTL mode operation The headphone controls operational mode. System enters SE mode when headphone jack is empty. When a set of headphone plugged into the jack, the system switched to BTL mode.
