16-Bits Stereo Audio DAC

Low Power Consumption

Low Voltage, Excellent PSRR

FEATURES

‧ Operation range: 2.5V~6.5V.

‧ Excellent Power Supply Rejection Ratio(PSRR).

‧ Low operating current.

‧ Low power consumption

‧ Low distortion.

‧ No zero crossing distortion.

‧ Wide dynamic range(16-bit resolution).

‧ Voltage Output .

‧ Cost efficient.

‧ Fast setting time permits 2*, 4*, and 8* oversampling

(serial input) or double speed operation at 4*

oversampling .

‧ Output voltage swing is proportional to supply voltage

‧ The minimum HIGH voltage of digital clocks

(WS,DATA and BCK)and the control inputs can be

1.8V at Vdd = 5V.

‧ As the power is up, the initial registers of the DAC are

0000Hex, so the DAC output will beVdd/2.

‧ Audio Format：I2S(MS6324)

Right Justified(MS6326)

‧ Space saving package SOP8, MSOP8, DFN8

APPLICATIONS

•Multimedia system

•MP3, PDA, Portable Digital Audio.

•Set top box.

DESCRIPTION

The MS6324/26 is a 16-bit voltage-output Digital-to-Analog Converter(DAC). It gives the excellent Power Supply

Rejection Ratio(PSRR). It features extremely low power dissipation, small package size and easy application. The

accuracy of the weight current sources, combined with the unique symmetrical decoding method, preclude zero-

crossing distortion and ensures high quality audio reproduction. As the power is up, the initial registers of the DAC are

0000Hex, so the DAC output will beVdd/2. These unique features, combined with its exceptional performance, make

the MS6324/26 ideally suited for use in portable audio equipment. MS6326 is pin and function compatible with

MS6323.
