HT82V737 is a low power consumption stereo DAC withan integrated earphone driver. The device utilizesCMOS technology specially for portable MP3 players,VCD and CD machines.It converts the 16 bits serial data into an analog outputvoltage by high precision D/A converter. It can be usedwith the Japanese input format: time multiplexed, twoscomplement, MSB first TTL level serial input. With its excellentfrequency response characteristics, theHT82V737 provides users a low cost means of implementinghigh quality audio voltage outputs. It also buildsin a class AB stereo driver and some application circuits,thus, requires minimal external components.The HT82V737 can support low voltage operation at2.4V so it is very suitable for portable battery poweredaudio device. A low supply in power down mode currentreduces power consumption. It is available in small16-pin NSOP package.
