DESCRIPTION

The MS6310 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 MS6310 is pin and function compatible with MS6311, Philips TDA1311.

Low Cost 16-Bit Stereo Audio DAC REV1 4 www.mosanalog.com.tw TIMING AND DATA FORMAT The MS6310 accepts input serial data formats of 16-bi t word le ngth. Le ft and right data words are tim e multiplexed. The MSB must always be first. The format of data input is shown in Figs. 2 and 3. With a HIGH level on the word select input (WS), data is placed in the left input register and with LOW level on the WS input, data is placed in th e right register (Fig. 1). Th e data in th e input reg isters are simultaneously latched in th e output registers which control the bit switches. Internal bias currents IBL and IBR are each adde d to the full scale output current IFS in order to achieve the maximum dynamic range at the outputs of OP1 and OP2 (Fig. 1). In this way the maximum dynamic range is achieved over the entire power supply range.
