PCM1753DBQR

The PCM1753, PCM1754, and PCM1755 (PCM175x) devices are stereo DACs based on an enhanced Δ-Σ architecture. This enhanced architecture employs 4th-order noise shaping and 8× oversampling quantization to achieve excellent dynamic performance and improved clock jitter tolerance. Thanks to support for industry-standard audio data formats and both 16-bit and 24-bit data, PCM175x devices interface seamlessly with audio DSPs and decoder ICs. PCM175x devices can be controlled in hardware mode or through a comprehensive set of user-programmable functions accessible via a 3-wire serial control interface supporting register writes. The PCM1753 is pin-compatible with the PCM1748, PCM1742, and PCM1741, except for pin 5.
