PCMD3180IRTWR explains

PCMD3180IRTWR is modulation of density of a high-powered, pulse (PDM) input comes time answer is used (TDM) or I2S output converter, support what input to PDM microphone to amount to 8 numbers passageway to undertake synchronous sampling. This parts of an apparatus is compositive but bias voltage of control of volume of process designing number, microphone, Suo Xianghuan (PLL) , but process designing connects filter high (HPF) , double 2 rank mode of filter, low defer filter, support the output sampling rate of highest 768 KHz. This parts of an apparatus supports time answer to use (TDM) , I2S or left-justify (LJ) frequency format, can undertake controlling through I2C or SPI interface. In addition, the lead plane of operation of interface of supportive frequency bus line mixes PCMD3180 to choose from machine mode. These compositive high-powered character, and the capacity that uses 3.3 V or power supply of 1.8 V only power source, make this parts of an apparatus becomes a space to suffer bounds frequency system to use medium superexcellent option in recording of far field microphone.

The rated temperature limits of PCMD3180IRTWR is – 40 ° C comes + 125 ° C, use the 24 WQFN that cite a base to enclose.
