DESCRIPTION
The MS6323 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. These unique features, combined with its exceptional
performance, make the MS6323 ideally suited for use in portable audio equipment. MS6323 is pin and function
compatible with MS6313.
