DESCRIPTION

●

SAMPLING FREQUENCY: 5kHz to 100kHz

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.
