Hi team,

My customers sometimes read 61h when they read these.
ADS1299-4 should be all 0.
Why does it happen?

Sincerely.
Kengo.

    Hi Kengo-san,

    Thanks for the post.

    The device may not be in a proper reset state after power-up. Do they follow the “Initial Flow at Power-Up” sequence shown in Figure 67 of the datasheet?  Please issue a RESET and see if the registers still read back the same value. Please also verify that the device ID register is correct, indicating it is a 4-channel device.

    Thanks
