Description

    The PCM1755 is a CMOS, monolithic, integrated circuit, which includes stereo digital-to-analog converters and support circuitry in a small 16-lead SSOP package.The data converters PCM1755 use TI's enhanced multilevel delta-sigma architecture, which employs 4th-order noise shaping and 8-level amplitude quantization to achieve excellent dynamic performance and improved tolerance to clock jitter. The PCM1755 accepts industry standard audio data formats with 16- to 24-bit data,providing easy interfacing to audio DSP and decoder chips. Sampling rates up to 200 kHz are supported. A full set of user-programmable functions is accessible through a three-wire serial control port, which supports register write functions.

    The PCM1755 is pin compatible with the PCM1748,PCM1742, and PCM1741, except for pin 5.
