产品概述
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.
