PCM1789PW
TEXAS INSTRUMENTS PCM1789PW 数模转换器, 24 bit, 192 kSPS, 串行, 4.5V 至 5.5V, TSSOP, 24 引脚
The is a high-performance single-chip 24-bit stereo audio Digital-to-analog Converter DAC with differential outputs. The 2-channel 24-bit DAC employs an enhanced multi-level, delta-sigma ΔΣ modulator and supports 8 to 192kHz sampling rates and a 24-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.
