  • ADS8904B: LDO voltage higher than supposed (3,5V instead of 2,85)

    Resolved
    Part Number: ADS8904B Tool/software: Hello, i'm using the ADS8904 in a design successfully, but i just realized that the voltage at the DECAP pin is way higher (3,4V - 3,5V) than it should be according to the datasheet (2,85V). 99% of the boards…

  • ADS8904B: Missing information in the datasheet and unable to read registers from ADC

    Part Number: ADS8904B Hi! The ADC is configured with these values in the registers: PD_CNTL = 0x00 SDI_CNTL = 0x00 (default SDI mode) SDO_CNTL = 0x0F (external SCLK, SDR, Data are output on SDO[0..3], SDO follow the source-synchronous protocol) DATA_CNTL…

  • ADS8904B: AIN input range

    TI Thinks Resolved
    Part Number: ADS8904B I'm looking at the circuit in section 8.2.1 of the datasheet. In this circuit, ”AIN to GND” is input up to 5V for REFIN = 4.5V. This exceeds the Absolute Maximum Ratings of Analog Input (AINP, AINM) to GND, VREF +…

  • ADS8904B: For single-ended use

    Resolved
    Part Number: ADS8904B We are considering new adoption of ADS8904B. From the specifications of the product under development, the ADC is single-ended input. SAR with high resolution (19bit or more) is required. I would like to use the ADS8904B with the…

  • ADS8904B: Single-ended input?

    Resolved
    Part Number: ADS8904B Other Parts Discussed in Thread: ADS8881 , Hi, I just want to confirm that it's *not* possible to drive the AINP input with a single-ended signal while the AINM input is connected to a fixed DC voltage. I believe this approach can…

  • ADS8904B: VREF above RVDD - 0.3V

    Resolved
    Part Number: ADS8904B Hi, For a variety of reasons, I would like to be able to use the same voltage rail (= 3.3V) that supplies the RVDD input to supply the VREF input as well. I realize this would violate the maximum recommended voltage for the VREF…

  • ADS8904B: SCK capacitance

    Resolved
    Part Number: ADS8904B Hello, Can we please request for the expected input capacitance of the SCK pin? Also, by adding a series resistance to the SCK input, can it possibly reduce/prevent the SCK clock noise from coupling to the ADC inputs? Thank you!
