Texas Instruments PCM1789
The PCM1789 is a high-performance, single-chip, 24bit, stereo, audio digital-to-analog converter (DAC) with differential outputs. The two-channel, 24-bit DAC employs an enhanced multi-level, delta-sigma (ΔΣ) modulator, and supports 8 kHz to 192 kHz sampling rates and a 16-, 20-, 24-, 32-bit width digital audio input word on the audio interface. The audio interface of PCM1789 supports a 24-bit, DSP format in addition to I2S, left-justified, and right-justified formats.| Part No. | PCM1789 |
