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, two¢s
complement, MSB first TTL level serial input. With its ex-
cellent frequency response characteristics, the
HT82V737 provides users a low cost means of imple-
menting 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.
