  • About PCM1807, PCM1808 and PCM1803A

    Other Parts Discussed in Thread: PCM1808 , PCM1803A , PCM1807 Please tell me following question about PCM1807, PCM1808 and PCM1803A. It is important spec to decide device by my customer. 1) Is 5V of analog supply voltage(VCC) affect SNR? My customer…

  • RE: understanding PCM1807/PCM1808/PCM1804 input voltage range

    Justin, Thanks very much, this clarifies the spec.

  • PCB design for PCM1807 & PCM1753. Does any schematic and PCB example and application note exist?

    TI Thinks Resolved
    Other Parts Discussed in Thread: PCM1753 , PCM1807 I want to create a product which uses PCM1807 and PCM1753. They are data converters for audio applications. However, they are complex devices in surface mount package. They require analogue and digital…

  • PCM1807 uses 23 bit signed, but why?

    Other Parts Discussed in Thread: PCM1807 The PCM1807 does not accept negative voltages, it operates from 0V to 3.3V so then why does it output 23 bit signed? Is there a comparable TI ADC part that outputs 24 bit un-signed? Thank you, Tony…

  • PCM1807 and other ADC decoupling caps Electrolytic or Ceramic

    Other Parts Discussed in Thread: PCM1807 Hello, I've lurked around here a bit, and today I found myself in a situation which I had no idea how to handle. TI tech support pointed back here for some possible enlightenment. My question is not a general…

  • PCM1865: TDM channel configuration

    Resolved
    Part Number: PCM1865 Other Parts Discussed in Thread: PCM1807 , Hello, I am trying to set-up my new design as it was configured on a earlier PCB version (with a different ADC), and I would like to know if I can select the order in the output TDM stream…

  • PCM1865: PCM1865 master clock output

    Resolved
    Part Number: PCM1865 Other Parts Discussed in Thread: PCM1807 Hello, I am trying to substitute the ADC I was using in a design by the PCM1865. In my previous design I was using a 12.288MHz oscillator as clock source to the ADC, and then outputed this…

  • RE: PCM1803A: Power-on/off Sequence

    Resolved
    Hi Kato-san, Unfortunately we don't have a lot of information on this functionality outside of what exists in the datasheet but the power sequencing requirements for this family are not very strict. This device was developed around the same time as…

  • RE: TIVA I2S

    Hello Alexandre, For PCM1807 the audio data interface has BCK, LRCK and DOUT and for configuration interface it has MS, MC and MD. Also I did notice that it is a 24 bit data interface which is something I am not sure if the legacy mode shall support…

  • RE: Analog to optical conversion

    We are looking to frequency of 10 to 500Hz. DC is not important. The application is an EMG. I think that we will purchase a PCM1807 or PCM3010 evaluation board to make the test. Thanks, Thierry
