  • ADS8353-Q1: ADS8353-Q1 SPI mode and timing

    TI Thinks Resolved
    Part Number: ADS8353-Q1 Hello, I have some troubles with the SPI interface of the ADS8353-Q1. I have found out that I can correctly read and write the user programmable registers using SPI mode 1. In this case, the read data is shifted 1 bit left…

  • ADS8353-Q1: Query in Noise Analysis

    TI Thinks Resolved
    Part Number: ADS8353-Q1 Hi, We are using ADS8353QPWRQ1 and is giving an external ADC reference voltage from an LDO through a buffer. The buffer output is fed to the ADC reference pin. The output broadband noise of the reference is filtered by a low…

  • ADS8353-Q1: Total Noise Calculation of ADC

    TI Thinks Resolved
    Part Number: ADS8353-Q1 Hi We are doing the noise analysis of ADS8353QPWRQ1 in which we are trying to calculate the total noise of the ADC system. We are performing the analysis based on the TI-precision-labs video: https://training.ti.com/ti-precision…

  • ADS8353-Q1: maximum acquisition time

    TI Thinks Resolved
    Part Number: ADS8353-Q1 Hello there, about the acquisition time, the EC table says that the maximum acquisition time is tacq=33*tCLK-tconv= 33*50ns-730ns=920ns (when 20Mhz, dual SDO mode) however, in figure 7-6 the tacq start at the end of tconv…

  • ADS8353-Q1: SPI SDO data launch edge

    Part Number: ADS8353-Q1 hello there, my test result of SPI SDO data latched edge is opposite with the datasheet. my test shows that the SDO latch edge is the rising edge of SCLK. however, the datasheet(figure 7-7. and table 10) say that the latch…
