| HT82V737 16-Bit Stereo Audio D/A Converter with Earphone Driver Features * Wide supply voltage range: 2.4V~5.5V * Low power consumption * 16-bit dynamic range * Low total harmonic distortion * Stereo audio outputs * Data in 2s complement format, TTL * Minimum number of external components is required * Low clock jitter sensitivity * Built-in highly efficient earphone driver * 16-pin NSOP package Applications * MP3 player * CD/VCD ROM and player * Satellite/cable STB * Digital portable audio/video equipment General Description 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.
