24-Bit, 96kHz Sampling
Enhanced Multilevel, Delta-Sigma, Audio
DIGITAL-TO-ANALOG CONVERTER
PCM1748
DESCRIPTION
The PCM1748 is a CMOS, monolithic, integrated circuit which
includes stereo Digital-to-Analog Converters (DACs) and support
circuitry in a small SSOP-16 package. 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 im-
proved 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.
