PCM1730E

ADCs/DACs - Special Purpose Overview

The PCM1730E is a stereo digital-to-analog converter (DAC) from Texas Instruments, utilizing delta-sigma modulation with an advanced segment architecture. It features 24-bit resolution and supports sampling rates up to 192 kHz. The device accepts standard, I2S, and left-justified data formats via a serial interface. Key electrical specifications include a typical dynamic range of 115 dB and a signal-to-noise ratio (SNR) of 115 dB at a 5 V analog supply. It operates on dual supplies: 5 V for analog circuits and 3.3 V for digital logic, with 5 V tolerant digital inputs.
