Description
AI
The PCM1789 is a high-performance, single-chip, 24-bit, 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.
The PCM1789 can be controlled through a three-wire, SPI-compatible or two-wire, I2C-compatible serial interface in software, which provides access to all functions including digital attenuation, soft mute, de-emphasis, and so forth. Also, hardware control mode provides two user-programmable functions through two control pins. The PCM1789 is available in a 24-pin TSSOP package.
