PCM1795SLES248A –MAY 2009–REVISED MARCH 2015
PCM1795 32-Bit, 192-kHz Sampling, Advanced Segment,
Stereo Audio Digital-to-Analog Converter Features 3 DescriptionThe PCM1795 device is a monolithic CMOS 32-Bit Resolution integrated circuit that includes stereo digital-to-analog• Analog Performance: converters (DACs) and support circuitryina small Dynamic Range: 123 dB SSOP-28 package. The data converters use TI’s
advanced segment DAC architecture to achieve– THD+N: 0.0005% excellent dynamic performance and improved• Differential Current Output: 3.9 mAPP tolerance to clock jitter. The PCM1795 provides• 8× Oversampling Digital Filter: balanced current outputs, letting the user optimize
analog performance externally. The PCM1795– Stop-Band Attenuation: –98 dB
accepts pulse code modulation (PCM) and direct– Passband Ripple: ±0.0002 dB stream digital (DSD) audio data formats, thus• Sampling Frequency:10 kHzto 200 kHz providing an easy interface to audio digital signal System Clock: 128, 192, 256, 384, 512, processors (DSPs) and decoder chips. The PCM1795
device also interfaces with external digital filteror 768fS With Autodetect
devices such as the DF1704, DF1706, and the• Accepts 16-, 24-, and 32-Bit Audio Data PMD200 from Pacific Microsonics™. Sampling rates• PCM Data Formats: Standard,I2S, and Left- upto 200 kHz are supported.A full set of user-Justified programmable functionsis accessible through an SPII2C serial control port that supports register write• DSD Format Interface Available
and readback functions. The PCM1795 device also• Interface Available for Optional External Digital supports the time-division-multiplexed (TDM)Filteror DSP command and audio (TDMCA) data format.• TDMCAor Serial Port (SPI™/I2C) User-Programmable Mode Controls:
