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's enhanced multilevel -Σ
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, I2S, 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 is
accessible through a 3-wire serial control port, which
supports register write functions.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of the Texas
Instruments standard warranty. Production processing does not
necessarily include testing of all parameters.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
