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 zerocrossing 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.

Left and right data words are time 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 the right register (Fig. 1). The data in the input registers are simultaneously latched in the output registers which control the bit switches. Internal bias currents IBL and IBR are each 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). In this way the maximum dynamic range is achieved over the entire power supply range. WS tr tHB tf LEFT RIGHT tLB tHW tSW BCK tcr LSB tSD MSB tHD DATA Fig.2 Timing and input signals.
