  • PCM4220: Trigger Start of ADC conversions

    TI Thinks Resolved
    Part Number: PCM4220 Hi, I am using multiple PCM4220 ADCs and need to be able to trigger them so that their conversions happen at the same time. Is this possible? Thanks

  • PCM4220: PCM4220 over flow not working

    Part Number: PCM4220 I cannot get the OVFL and OVFR to go HIGH. I connected a 7.5Vpp differential signal, 20kHz, on its input and OVFL/R do not go HIGH. 7.5Vpp is the maximum do to my input op-amp. I have setup the ADC for 200kHz sample and the MCKI …

  • RE: PCM4220: Unexplained Idle Noise

    ok

  • PCM4220: high temperature operation

    Part Number: PCM4220 I am using the PCM4220 with a 12.8MHz master clock in order to generate 200kHz sample rate. The part is specified up to 216kHz. The device is operating in master mode. See the attached schematic. The device is expected to run quite…

  • RE: PCM4220: PCM4220 clocks

    We have devices such as TLV320ADC3120 that can support sample rates of 192 Khz at Sample Rate of 48khz. At 200Khz Manual setup of PLL is needed. It is not recomended

  • PCM4220: Dynamic range calculation

    Part Number: PCM4220 Hi Team, A customer would like to know how the dynamic range is calculated. At 192kHz the Dynamic range is specified as 112dB. What is the voltage on VCOML and VCOMR and what is the RMS noise? In the past, the customer used this formula…

  • PCM4220: Digital output when input exceeds the max input level

    Part Number: PCM4220 For the PCM4220PFB, the analogue supply is 4V and the VCOM is 1.95V. Each input is 2.8Vpp or 5.6Vpp differential. What would happen to the ADC conversion data if the input is 3Vpp? What would happen to the ADC conversion data if a…

  • PCM4220: PCM4220-Noise

    Part Number: PCM4220 Hi TI Team, When the temperature of PCM4220 reaches 60 degrees, PCM4220 makes noise. Reduce the temperature of PCM4220 to 25 degrees and return to normal. Please help to analyze the reason, thank you!

  • PCM4220: DC offset with HPF enabled

    Part Number: PCM4220 Can anyone at TI chime-in on the DC offset of the PCM4220/4222? We have the digital high-pass filter enabled in our design, but we're still seeing a few hundred counts of offset that varies part-to-part and channel-to-channel.…

  • PCM4220: PCM4220 THD+N issue

    TI Thinks Resolved
    Part Number: PCM4220 Other Parts Discussed in Thread: PCM4222 Hi team, We meet some issues regarding THD+N of this part. In datasheet, it shows THD+N is -10xdB at 997Hz, -1dB input and -9xdB at 997Hz, -20dB input no matter which sample rate is used. …
