DESCRIPTION

The MS6311 is a 16-bit voltage-output Digital-to-Analog Converter(DAC). The MS6311 is fabricated in a 0.8µm CMOS process and features extremely low power dissipation, small package size and easy application. The accuracy of the matched coarse 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 MS6311 ideally suited for use in digital audio equipment. MS6311 is pin and function compatible with the Philips, TDA1311.

  • 4 - www.mosanalog.com.tw TIMING AND DATA FORMAT The MS6311 accepts input serial data formats of 16-bit word length. Left and right data words are tim e multiplexed. The MSB (b it 1) must always b e first. Th e format of dat a input is shown in Figs. 2 a nd 3. With a H IGH 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 the right re gister (Fig. 1). The data in the i nput registers are simultaneously latched in the output re gisters which control the bit switches. Internal bias currents IBL and I BR are eac h added to the full scale output current IFS in order to achieve the maximum dynamic range at the outputs of OP1 and OP2(Fig. 1). The reference voltage Vref (Fig. 1) is approximately 2/3 VDD. In this way the maximum dynamic range is achieved over the entire power supply range.
