DESCRIPTION
The PCM1770 and PCM1771 devices are CMOS,
monolithic, integrated circuits which include stereo
digital-to-analog converters, headphone circuitry, and
support circuitry in small TSSOP-16 and VQFN-20
packages.
The data converters use TI鈥檚 enhanced multilevel
鈭?危
architecture, which employs noise shaping and
multilevel amplitude quantization to achieve excellent
dynamic performance and improved tolerance to clock
jitter. The PCM1770 and PCM1771 devices accept
several industry standard audio data formats with 16- to
24-bit data, left-justified, I
2
S, etc., providing easy
interfacing to audio DSP and decoder devices.
Sampling rates up to 50 kHz are supported. A full set of
user-programmable functions are accessible through a
3-wire serial control port, which supports register write
functions.
