DESCRIPTION The MS6610 is a 16-bit current-output Digital-to-Analog Converter(DAC). The MS6610 is fabricated in a 0.8µm CMOS process and features extremely low power dissipation, small package size and ease of application. The accuracy of the matched coarse 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 MS6610 ideally suited for use in digital audio equipment. MS6610 is pin and function compatible with the Philips, TDA1545.

Left and right data words are time multiplexed. The MSB(bit 1) must always be First. The format of data input is shown in Figs. 2 and 3. With a LOW level on the word select input(WS) input data is placed in the right input register and with HIGH level on the WS input data is placed in the left register. 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). The reference output voltage Vref(Fig. 1) is 2/3 VDD. In this way the maximum dynamic range is achieved over the entire power supply range.
