APPLICATIONS
DESCRIPTION
The PCM1741 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 improved toler-
ance to clock jitter. The PCM1741 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-program-
mable functions are accessible through a 3-wire serial
control port that supports register write functions.
