TI PCM1690DCAR

The PCM1690 device is a high- performance, singlechip, 24- bit, eight- channel, audio digital- to- analog converter (DAC) with differential outputs. The eightchannel, 24- bit DAC employs an enhanced, multilevel 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 the PCM1690 supports the time- division- multiplexed (TDM) format in addition to the standard I²S, left- justified, right- justified, and DSP formats. The PCM1690 can be controlled through a three- wire, SPI- compatible interface, 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 a subset of user- programmable functions through two control pins. The PCM1690 is available in a 12- mm × 8- mm (12- mm × 6- mm body) HTSSOP- 48 package.
