MOS INTEGRATED CIRCUIT
µPD6379, 6379A, 6379L, 6379AL
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

µPD6379L
µPD6379AL
+5.0 V (VDD = +4.5 to 5.5 V)
µPD6379
µPD6379A
Few external components
Internal output operational amplifier
