تراشه صوتی UPD6379AGR پکیج SOP-8

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

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 6379AL at VDD +3.3 V)

LRCK Supply voltage +3.3 V (VDD +5.0 V (VDD 5.5 V) LRCK = L when L-ch data is input LRCK = H when L-ch data is input

Few external components Internal output operational amplifier Only one electrolytic capacitor required for smoothing reference voltage, instead of two capacitors required by existing D/A converters Small package: 8-pin plastic SOP mm (225))
