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 4£[ bridged-tied (BTL) speaker or 2 * 90mW into stereo 32£[ 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.
