Description

The MS6337 is a 16-bits voltage-output Digital-to-Analog 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 4Ω bridged-tied (BTL) speaker or 2 * 90mW into stereo 32Ω single ended (SE) headphone. The 16-bit 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 zero-crossing 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.
