  • PCM1804: PCM1804DBR – VCOM behavior during reset, analog input pin state, and VCOM internal circuit

    TI Thinks Resolved
    Part Number: PCM1804 Hi Team I have the following questions regarding the PCM1804DBR: 1. VCOM behavior when RST pin (Pin 19) is pulled "Low" (Reset state) VCOM normally outputs approximately 2.5V during normal operation. Could you please clarify…

  • PCM1804: Balanced line level input for PCM1804

    Part Number: PCM1804 Other Parts Discussed in Thread: PCM1822 , TAA5242 I'm looking to use the PCM1804 for a balanced line level (XLR) input. Ideally without a negative voltage supply. Should I use an op-amp to add the DC offset from Vcom or can I just…

  • PCM1804: PCM1804_ Bit‑Clock Margin When Operating at 64 fs in Follower Mode

    Resolved
    Part Number: PCM1804 According to the datasheet, the minimum bit‑clock period in follower mode is specified as 1/64 fs. If we configure the bit clock to 64 fs, there is a possibility that the actual operating value may slightly fall below this minimum…

  • PCM1804: Differential input with single ended driver

    Part Number: PCM1804 Other Parts Discussed in Thread: PCM1809 Tool/software: Hi I got single ended source. Is any benefit to convert it to differential with front end op amps(datasheet recommended)? Or simply connect in- to analog source gnd via capacitor…

  • PCM1804: Multiple cascade

    TI Thinks Resolved
    Part Number: PCM1804 Tool/software: Dears， The customer's application scenario is one processor with one I2S connected to multiple PCM1804. Can it be supported and how can it be implemented.

  • PCM1804: VcomR and VcomL join in case of unbalanced connection

    TI Thinks Resolved
    Part Number: PCM1804 Other Parts Discussed in Thread: PCM1802 Tool/software: Hi I need to connect battery powered amp to PCM1804. But I have one op amp only. I want to connect Vcom to amp GND to lift it to 2.5V. That works well with PCM1802. But PCM1804…

  • PCM1804: PCM1804 encounters output distortion problem

    Part Number: PCM1804 Hi Team, The PCM1804 specification describes that the maximum input amplitude is 5VPP. In practical applications, when the input is greater than 3VPP, the output will be distorted. Please help to confirm the reason.

  • PCM1804: 0dBFS input level

    Part Number: PCM1804 The 0dBFS level of the PCM1804 is a little ambiguous from the data sheet. The banner specifications give +/-2.5 V (Vpk, Vpp, Vrms, unspecified): Whereas the recommended operating conditions specifies 5 Vpp: The electrical…

  • PCM1804: Spice model for this ADC

    Part Number: PCM1804 Other Parts Discussed in Thread: PCM1820 Tool/software: Is there a spice model for this ADC? I am looking to run some simulations and have only found the IBIS model for it. Could I also get the spice model as well?

  • PCM1804: If PCM1804 dual ADC channel is separately working?

    Part Number: PCM1804 If PCM1804 dual ADC channel is separately working? Or not work at same time?
