Hello MJ,
You have different options such as PCM5101, PCM5102 and PCM1789.
While they all have better or similar major spec, PCM510x needs a single supply of 3,3v ( That is 3.3V analog and 3.3V digital supplies), PCM1789 needs dual supplies ( 5V analog…
Other Parts Discussed in Thread: PCM1789 I'm using PCM1789 in my design with PIC32. I've initialized I2S bus according to PCM1789 datasheet, format: I2S 16bit, (SCK=12.288000MHz, BCK=3.0MHz, LRCK=48KHz). It's been checked with my oscilloscope. When I trying…
The spec for the THD+N for this part is given both as .001% and -94db. If I do my math correctly, 20 * log (.001%) is -100 db, not -94 db. So which is it? Also, can the analog VCC be run at 3.3v instead of 5V, and what degradation could one expect by…
Other Parts Discussed in Thread: PCM1789 I have an application involving a PCM1789, wherein the analog supply is not always available. As presently designed, the product can run for an indefinite period period of time with the digital supplies (VDD) at…

Part Number: PCM1742 Other Parts Discussed in Thread: PCM1789 Hi,
When all-zero data was input to the PCM1742, 70Hz with a noise level of about -108dB and odd-order harmonics appeared from the delta-sigma modulation output. Is this a known symptom? These…
Other Parts Discussed in Thread: PCM1789 , OPA2134 , MC33078 , PCM5102A , PCM5102 , PCM5122 , PCM5121 We are designing the PCM1789 Stereo Audio DAC into a new product.
The application data recommends using a second order Butterworth low pass filter at the output…
