  • ADS8910B: SDO pin is not operate.

    Resolved
    Part Number: ADS8910B The CONVST, CS, and SCLK pins are operating as recommended, but the SDO pin is not. After power-up, the RVS pin remains low. In the datasheet page 25; 7.4.1 RST State "In RST state, all configuration registers are reset to their…

  • ADS8910B: SPI usage

    TI Thinks Resolved
    Part Number: ADS8910B Do we have any application notes about the usage of SPI interface in ADS8910B? My MSP432/C2000 SPI is byte bound. In other words, I only can read 1 bytes at a time. I could not read 18 bit at a time. So, I guess I will have to read…

  • ADS8910B: Full Scale Range

    Resolved
    Part Number: ADS8910B Hi; On the ADS8910B datasheet page-22, you have: FSR=+/-Vref I will interpret it as: FSR = Vref -(-Vref) = 2*Vref So this matches the 1LSB formula on page-23 1LSB = (2*Vref)/(2^18) = Vref/2^17 Now, if I connect 2.5V reference voltage…

  • RE: ADS8910B: Setting ADS8910B to Quad-SSI mode with MSP432E401Y

    Resolved
    Hi Michael, You can use the standard SPI on your MCU and the Zone 2 feature of the ADS8910B to meet your throughput requirements. We are looking at using the QSSI feature on the MSP432 to support the Quad-SDO feature of the ADS8910B, but this will take…

  • ADS8910B: CONVST and ~CS connection and RST state

    Resolved
    Part Number: ADS8910B In the datasheet page 25; 7.4.1 RST State ...... "To exit RST state, the host controller pulls the RST pin high, with CONVST and SCLK held low and CS held high, as shown in Figure 39." which means we have to drive CONVST…
