MS4344 is a stereo digital-to-analog converter chip, including interpolation filter, multi bit digital-to-analog converter, output analog filter. The MS4344 supports most audio data formats. The MS4344 is based on a four-order multi-bit Delta-σ modulator with a linear analog low-pass filter, and the chip can automatically adjust the sampling rate between 2KHz and 200KHz by detecting the signal frequency and the master clock frequency. The MS4344 can operate at 3.3V and 5V. These features make it an ideal choice for wireless devices such as DVD player decoders and digital communication devices.
