FEATURES

• Excellent Power Supply Rejection Ratio(PSRR) •Easy application :

• Voltage Output single 2.8 to 5.5 rail power supply

• Space saving package(SOP8) output and bias current are proportional to supply voltage

• Low power consumption integrated current-to-voltage converter

• Low total harmonic distortion

• Wide dynamic range(16-bit resolution)

• No zero crossing distortion

• Wide operating tempera t ure range(-40℃ to 85℃)

• Internal bias current ensures maximum dynamic range

• Fast setting time permits 2*, 4*, and 8* oversampling(serial input) or double speed operation at 4* oversampling

• Compatible with most of the Japanese input formats; time multiplexed, two's complement, TTL

• The full scale output voltage can be mask optioned

• Cost efficient

APPLICATIONS

VCD Player, DVD Player, CD-ROM, DVD-ROM, CD-RW, DVD-RW, Motherboard.
MP3, PDA, Portable Digital Audio.

DESCRIPTION

The MS6313 is a 16-bit voltage-output Digital-to-Analog Converter(DAC). The MS6313 is with excellent Power

Supply Rejection Ratio(PSRR). It is fabricated in a 0.8

µ

m 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 MS6313 ideally suited for use in digital audio
equipment. MS6313 is pin and function compatible with the Philips, TDA1311.
