DESCRIPTION
The MS6309/10 is a voltage-output Digital-to-Analog Converter (DAC). The accuracy of the weight current
sources, combined with the unique symmetrical decoding method, preclude zero-crossing distortion and ensures high
quality audio reproduction. the initial registers of the DAC are 0000Hex, so the DAC output will be Vdd/2.
