DESCRIPTION

The MS6337 is a 16ꢀbits voltageꢀoutput DigitalꢀtoꢀAnalog Converter (DAC) integrated class AB stereo headphone

driver and mono speaker power amplifier. It can drive 1.8W of continuous average power into a mono 4ꢁ bridgedꢀtied

(BTL) speaker or 2 * 90mW into stereo 32ꢁ single ended (SE) headphone. The 16ꢀbit DAC supports popular formats

as I2S, Right Justified.

The MS6337 is with the excellent Power Supply Rejection Ratio(PSRR) and features extremely low power dissipation,

small package size and easy application. The accuracy of the matched coarse current sources, combined with the

unique symmetrical decoding method, preclude zeroꢀcrossing distortion and ensures high quality audio reproduction.

These unique features, combined with its exceptional performance, make the MS6337 ideally suited for use in digital

audio equipment.
