DATA SHEET
MOS INTEGRATED CIRCUIT
µPD6379, 6379A, 6379L, 6379AL
2-CHANNEL 16-BIT D/A CONVERTER FOR AUDIO APPLICATION
The µPD6379 and 6379A are 2-channel 16-bit D/A converters for digital audio signal demodulation. These D/A
converters employ the resistor string conversion method which has been tested by existing model µPD6376 but they
are more compact and require fewer external components than the µPD6376. In addition, low-voltage models, the
µPD6379L and 6379AL (minimum operating supply voltage = +3.0 V) are also available for applications in portable
systems.
FEATURES
• Resistor string conversion method
• 0-point digital shift circuit
× 4 oversampling
Sampling frequency: 200 kHz MAX.
• Signal processing format for 2’s complement, MSB first, and backward justification data accommodated
• Left and right in-phase output
• High performance (at VDD = +5.0 V)
S/N ratio: 100 dB TYP.
Dynamic range: 96 dB TYP.
• Low-voltage models available
• Bipolar LR clock (LRCK)
• Low power dissipation: 10 mW TYP.
(with µPD6379L, 6379AL at VDD = +3.3 V)
