HT82V737 is a low power consumption stereo DAC with an integrated earphone driver. The device utilizes CMOS technology specially for portable MP3 players, VCD and CD machines. It converts the 16 bits serial data into an analog output voltage by high precision D/A converter. It can be used with the Japanese input format: time multiplexed, twos complement, MSB first TTL level serial input. With its excellent frequency response characteristics, the HT82V737 provides users a low cost means of implementing high quality audio voltage outputs. It also builds in a class AB stereo driver and some application circuits, thus, requires minimal external components. The HT82V737 can support low voltage operation at 2.4V so it is very suitable for portable battery powered audio device. A low supply in power down mode current reduces power consumption. It is available in small 16-pin NSOP package.
