ADS1293: 12 Leads ECG

Part Number: ADS1293

Hi team,

Use three ADS1293 to build 12 lead ECG. The CPU uses STM32. ADS1293 communicates with STM32, SDO / SDI / SCLK connects SPI pin of STM32 respectively, and DRDYB/CSB1/CSB2/CSB3 connects GPIO port of STM32. Is this connection feasible?


Best Regards,

  • Hello Amy,

    Thank you for your post.

    Yes, please follow Figure 88 as a reference connection diagram for 12-lead ECG systems using ADS1293. Section 9.2.3 gives additional information about synchronizing the three devices from a common clock source. The slowest data rate channel on the master ADS1293 device should be configured as a SYNCB output pulse.

    Best regards,
