  • ADS1262: Timing questions about ADS1262 SPI interface

    TI Thinks Resolved
    Part Number: ADS1262 Tool/software: Dear Team, I've a question about the SPI timing of the ADS1262 device. The datasheet of the ADC says (Pg 10) that the delay time td(CSSC) from CS falling edge and first SCLK rising edge shall be 50 ns. But the sampling…

  • ADS1262: : ADS1262 (STM32H723, SPI1) — AINX–AINCOM reads 0 V even though 1.25 V is applied (looking for guidance on RDATA framing and AINCOM enable)

    Part Number: ADS1262 Tool/software: Hello, I’m bringing up a three ADS1262 with an STM32H723 (SPI1 / HAL). I apply ~1.25 V between AINX–AINCOM, but the measured value is always 0 V (code = 0). This post is only about the voltage reading stuck at zero…

  • ADS1262: Input impedance variation

    TI Thinks Resolved
    Part Number: ADS1262 Tool/software: Hi, We have been using the ADS1262 on a datalogging product successfully for a few years. A recent batch of boards, which have this part fitted, have all exhibited a wildly different input impedance from those we…

  • ADS1262: Powering ADS1262 off of USB

    TI Thinks Resolved
    Part Number: ADS1262 Hello, I am designing a board using the ADS1262, and in my design, I would like to power the board via USB. I'm wondering if the input AVDD can reliably be powered by USB 5V, or if voltage variations could lead to unstable readings…

  • ADS1262: ADS1262

    TI Thinks Resolved
    Part Number: ADS1262 Hello, I need to design 4 ADCs in single PCB board. Any gap maintains (Placement) between two ADC's. I need to take care any extra points, please suggest to me.

  • ADS1262: What is the function of AINCOM

    TI Thinks Resolved
    Part Number: ADS1262 Tool/software: Dears, For ADS1262IPW, if it is single-ended input, all ten channels AIN0-AIN9 can be used, right? AINCOM is the reference ground terminal? Many thanks!

  • ADS1262: Schematic review request

    TI Thinks Resolved
    Part Number: ADS1262 Tool/software: Hi everyone, I'm currently working on a circuit design intended to accurately read the values of a load cell while minimizing noise.This values will be read at a max rate of at least 1000sps (or 1200 as I believe…

  • ADS1262: Open sensor causes overrange reading on Thermocouple channel 1 and increases value on thermocouple 2 channel 2

    Part Number: ADS1262 Tool/software: I have a multi channel system running on a stm32 mcu based pcb. For the most part it takes and displays thermocouple readings well but I've noticed when I run the functions in my code to read both channels it tends…
