2-CHANNEL 16-BIT D/A CONVERTER FOR AUDIO APPLICATION

The

碌

PD6379 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

碌

PD6376 but they

are more compact and require fewer external components than the

碌

PD6376. In addition, low-voltage models, the

碌

PD6379L and 6379AL (minimum operating supply voltage = +3.0 V) are also available for applications in portable

systems.

FEATURES

鈥?Resistor string conversion method
