113dB SNR Stereo DAC (H/W Control) - PCM1793

PCM1793 (ACTIVE)

113dB SNR Stereo DAC (H/W Control)

 

Recommended alternative parts

  • PCM5102  -  32-bit resolution, integrated PLL, higher sampling rate, 112dB SNR
  • PCM1791A  -  SPI and I2C controlled
  • DSD1793  -  Same functionality, different pinout

Description

The PCM1793 is a monolithic CMOS integrated circuit that includes stereo digital-to-analog converters and support circuitry in a small 28-lead SSOP package. The data converters use TI’s advanced segment DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter. The PCM1793 provides balanced voltage outputs, allowing the user to optimize analog performance externally. Sampling rates up to 200 kHz are supported.
