  • ADS52J90: About input impedance

    TI Thinks Resolved
    Part Number: ADS52J90 Hi All, Please tell me the input impedance value of ADS52J90. I checked the past E2E, but I couldn't find the value. https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/660533/ads52j90-input…

  • ADS52J90: Configuring ADS52J90 for Non-Continuous Data Digitization in 32-Channel Mode

    Part Number: ADS52J90 Hello, I am attempting to utilize the ADS52J90 in a 32-channel mode to digitize 32 distinct analog values coming from a test chip. The data received from the test chip is not continuous in nature. Whenever the data is ready, the…

  • ADS52J90: Even and Odd Channel mapping

    Resolved
    Part Number: ADS52J90 Hello, In a previous E2E forum post, I was told that, when using the ADS52J90 in 32 channel mode and setting the ADC into "ramp" test pattern mode, odd samples from the ramp pattern will come from the odd samples of each ADC core…

  • ADS52J90: Startup Initialization

    Resolved
    Part Number: ADS52J90 I have two questions regarding the ADS52J90 startup sequence: What is the consequence of the startup power rail ramp sequence not being strictly followed? That is, if the 1.2DVDD, 1.8DVDD, and 1.8AVDD all are set to the right voltage…

  • ADS52J90: Toggle and ramp modes expected behavior in 32 Channel mode

    Resolved
    Part Number: ADS52J90 Hello! I have been using an ADS52J90 in a design with an FPGA receiver. I previously simulated the FPGA receiver to ensure that the data would be read back properly. I am using the ADC in 32 channel mode with 12 bit resolution. …

  • ADS52J90: LVDS Clock to Data out Variance

    Part Number: ADS52J90 Hello! Looking at the datasheet for the ADS52J90, I can't seem to find a spec for the variance between the edge of the LVDS data clock and the data transition for the LVDS serial output channels. This is important for me to set…

  • ADS52J90: Input signal larger than ADS52J90 dynamic range

    Part Number: ADS52J90 Other Parts Discussed in Thread: TINA-TI I have a single-ended analog signal range from 1.25V to 2.5V, and the ADS52J90 dynamic range is -1V to 1V. I can not directly connect them. So the question is Can I use a differential ADC driver…

  • ADS52J90: Load Capacitor Selection

    TI Thinks Resolved
    Part Number: ADS52J90 Hello, I am working with the ADS52J90 and connecting the LVDS to a SoM on another board. I noticed the datasheet specifies a 4pF load capacitor between each output and ground. I am wondering where this value was derived from? Additionally…

  • ADS52J90: Vref and more than one chip on board

    Part Number: ADS52J90 Hello, I understand that the ADS52J90 does not have a Vref input and only external Vref for the ADC conversion. Is this device meant to be used with additional ADS52J90. In other words: If I have two in a design, wouldn't a common…

  • ADS52J90: Gain and offset drift over temperature data

    Part Number: ADS52J90 Hello, I am looking for any data on the ADS52J90's characterization of gain and offset drift over its temperature range. The datasheet mentions that the ADC has 0.1dB gain drift over the temperature range, but I was hoping to get…
