DESCRIPTION
Passband Ripple: ±0.02 dB
The DSD1608 is a CMOS, monolithic, 8-channel
digital-to-analog converter which supports both PCM
audio data format and direct stream digital (DSD) audio
data format. The device includes an 8× digital
interpolation filter and a digital DSD filter with three
selectable frequency-response curves, followed by
Texas Instruments’ enhanced multilevel delta-sigma
modulator, which employs 4th-order noise shaping and
8-level amplitude quantization to achieve excellent
dynamic performance and improved tolerance to clock
jitter. Sampling rates up to 192 kHz for the PCM mode
and 64 × 44.1 kHz for the DSD mode are supported. A
full set of user-programmable functions is accessible
through a 4-wire serial control port, which supports
register write and read functions. The DSD1608
supports the time-division-multiplexed command and
audio data (TDMCA) format. The DSD1608 is available
in a 52-pin TQFP package.
