The data converters utilize Texas Instrument’s enhanced multilevel delta-sigma architecture that employs fourth-order noise shaping and 8-level amplitude quantization to achieve excellent dynamic performance and improved tolerance to clock jitter.
The PCM1748 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 100kHz are supported.
A full set of user-programmable functions are accessible through a 3-wire serial control port that supports register write functions.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Inst...
