SmartAutomotive™ Automotive MEMS Motion Sensors

Review of the technical datasheet does not reveal significant differences between the IAM-20680HT and IAM-20680HP devices.
Will you please explain at the high-level if there is a difference in the testing and selection that parts undergo to be categorized HT vs HP?
And are there some functions that are not enabled in one device vs the other?

Hello, community, I hope, that somebody has a solution for this.
I've faced a situation in which sometimes randomly z axis of the IAM-20680 gyro axis becomes stuck.
As on the picture below (sticked axe in rest.jpg) you can see that in rest all of the axis show pretty the same behaviour in terms of range of noise.
But when I'm starting to rotate the IMU around all of 3 axis, one of them shows the same values as it would be in rest (you can see it on the sticked axe in moving.jpg - line wz).

Hi There,

I want to know FITs or MTBF Value for IAM-20680HT.
Can you please let me know where can I get it ?
or if TDK has some experimental data, can some one please share to me.
Thanks,
Suhant

1. Is it mandatory to keep sensor at flat surface to perform self test?
2. How Self-test can be utilized for sensor re-calibration at user end?

My understanding is, change of user programmable offset is needed when self-test fails, please clarify.

Thanks,
Anurag

IAM20680 giving 0 on X and Z axis and 3 on Y axis when it is at rest.
Gyro sensitivity is 131 LSB/dps (FS_SEL = 0) and accelerometer is 16,384 LSB/g (AFS_SEL=0).
I'm recording 200 samples at every 10ms and then calculating average of it, to calculate gyro and accel values.
I don't know how to verify gyro values as well.
I've attached a screenshot of results, I have also attached ST and normal mode results at rest. Please help me out.

Our company connects ICM-20948 through i2c interface.
We implemented driver in Linux kernel 5.15.74.
And, it is used in the i2c master enable state.

There's nothing wrong with normal times.

Has anyone heard any details about when the IAM-20685 will be available, or a data sheet will become available?

Hi Everyone,
I am using EV-IAM-20380HT board to evaluate IAM-20380 Gyroscope. I have following issues with EV-IAM-20380HT:
1. can not find the datasheet of EV-IAM-20380HT, however, the datasheet of IAM-203380 is available.
2. get WHO-AM-I register value is 253 (0xFD), not the 181(0xB5) as indicate in the datasheet, through I2C reading.
3. the SDA and SCK of EV-IAM-20380HT is directly connected to the master’s SDA & SCK (3.3V logic) in my application. Do the SDA and SCK need to pull up to +3.3V with 2x 10k resistors respectively?

Good evening,

We have been developing an application using the IAM-20680HT and HP devices for ~18 months, but have started to notice recently issues matching the acceleration values from the IAM devices, to other accelerometers used in our product.

We think the issue may be related to filter attenuation. The datasheet does not specific if the low pass filter is a 2, or 4 pole filter - and thus wether the roll off rate is 20dB/decade, or 40dB/decade - please may you confirm?
