I have previously used a large quantity of LSM6DSV16XTR products from batch 426, and their data was completely normal. My device utilizes 16 gyroscopes simultaneously. Recently, I started using products from batch 509, and they have exhibited a peculiar phenomenon. Specifically, it includes two parts: (1) When the temperature slowly increases from -40°C to 85°C, observing the data of a gyroscope at rest, some gyroscopes show data jumps at certain temperature points (the jump temperature point varies for each gyroscope). For example, the data may jump from -0.98°/s to -0.08°/s. (2) For the same gyroscope, at the same temperature, the bias data varies significantly at different times. This phenomenon does not occur in every gyroscope, but it greatly troubles me because I cannot record and compensate for the bias data in the temperature chamber, as these biases have become highly irregular. This phenomenon did not occur in batch 426. Does anyone know why this is happening?
