1 / 20 page 24-Bit, 192kHz Sampling, Enhanced Multi-Level, Delta-Sigma, Audio DIGITAL-TO-ANALOG CONVERTER 49% FPO PCM1739 ® TM DESCRIPTION The PCM1739 is a CMOS, monolithic, integrated circuit which includes stereo 24-bit audio digital-to- analog converters and support circuitry in a small SSOP-28 package. The data converters utilize Burr- Brown’s enhanced multi-level delta-sigma architec- ture, which employs 4th-order noise shaping and 8-level amplitude quantization to achieve excellent dynamic performance and improved tolerance to clock jitter. The PCM1739 accepts industry-standard audio data formats with 16- or 24-bit data, providing easy interfacing to audio DSP and decoder chips. Sampling rates up to 192kHz are supported.
