  • ADS127L11: ADS127L11 (24 bit ADC)

    TI Thinks Resolved
    Part Number: ADS127L11 We are trying to read the ADC value from PSoC 5 (Cypress microcontroller). But we are unable to read the right values. Count is changing , when we change the input voltage. But did not get any pattern. Difficult to understand that…

  • RE: ADS127L11: Daisy chain not working beyond two devices

    Hello AW, I assume you have been able to get your design working. Please let me know if you have any additional questions. Regards, Keith

  • RE: ADS127L11: Not Getting resolution in microvolts.

    Hello Haresh, Sorry, but you will need to contact Cypress for any specific help in configuring their products. However, we do have example code for the ADS127L11 that you can modify to use to develop and debug drivers for the Cypress MCU. https://www…

  • ADS127L11: Should use four oscillator or 1 oscillator + clock buffer

    Resolved
    Part Number: ADS127L11 Hello, Should use 4 oscillator or 1 oscillator + clock buffer? I suppose 4 oscillator will be better for layout and EMC. Both solution can be synchronized by start signal. Let me know your recommendation.

  • ADS127L11: adc accuracy calculation

    Resolved
    Part Number: ADS127L11 Hello, Based on below table from datasheet. if analog input = 4.096V, - the typical INL error = 0.9ppm *4.096V = 3.686uV - the typcal offset error = 30uV - the typcal gain error = 200ppm * 4.096 = 819.2uV so, total error = INL error…

  • RE: ADS127L11: ADS127L11 is not responding

    Resolved
    Hello Realathu, Yes, I can provide some updates once this is resolved. Please note that the device can be damaged if the AVDD supply is accidentally shorted to the CAPA pin (these pins are directly next to each other on the ADC). Also, we have example…

  • RE: TPS65133: power solution for opa810 & ths4551 & ads127L11

    Resolved
    Hi Liping, LDO will help to reduce more ripple because of its PSRR, so I think it will be OK. BR Patrick

  • ADS127L11: How to calculate the latency

    TI Thinks Resolved
    Part Number: ADS127L11 Hi team, customer test the latency of ADS127L11 and found the result is different from the data in datasheet. Customer used synchronized mode and use 25MHz as Fclk, 400ksps as data rate, OSR=32, Sinc4. According to datasheet, the…

  • RE: THP210: Paired with ADS127L11, potential error/oscillation?

    Resolved
    HI Adam, I just got back to office. Yes, from the THP210 perspective, using a 25kΩ and 50kΩ nominal resistors at the VOCM pin places the output common-mode at 3.3278V when accounting for the impedance loading of the internal 5MΩ+5MΩ voltage divider on…
