Hi,   A couple of ADXL362 show abnormal outputs on Y and Z axis after working for about 2 weeks in the field. These outputs were no problem (showed correct values) at my shipping test but returned abnormal devices output fix values, for instance Y=0xF800 and Z=0x67FF, and these values do not change even though adding acceleration intentionally.… (Show more)

Good morning,   I am using your sensor mounted on a small PCB together with an ATmega328P micro-controller to build a small number of inclinometers for manual sheet metal bending. I am only interested in x (roll) and y (pitch) angle output via an attached display.   1. I have done a 6-point-tumble 2-point calibration with a leveling block on a… (Show more)

I'm sure everyone has seen those small digital angle meters with reported accuracy typically 0.1 or 0.2 degrees. I'm looking to design something that can have an accuracy of 0.05 degrees and I think perhaps the ADXL350 might be a good candidate.   My objective is to keep the BOM below $50 so that eliminates some of the really high accuracy… (Show more)

I'm a developer to make the application with Analog Device's Sensor. Few days ago, I found the wrong phenomenon in the sensor. So, I would like to ask your help whether a problem of reliability or a reported similar case. I made a product with ADXL35x, cased by die casting and molding urethane material.   1. We tested 10 D.U.T.(device under… (Show more)

Hi, We found a serious problem about  ADIS16467-1BMLZ: When angular rate over 200 deg/s,ADIS16467-1BMLZ’s Gyro output will reverse and jump to opposite side! We have four ADIS16467-1BMLZ,and all of them have the same problem! And we also have some ADIS16460AMLZ ,we test ADIS16460AMLZ and ADIS16467-1BMLZ in the same condition,the ADIS16460AMLZ is… (Show more)

Hi there, I have a question about ADXL356. ・Please tell me the proper pin setting when the Self test function is not used. Is it okay to connect ST pin to GND?   Best regards, Tarzan

Hi, I am just getting started with using ADXL372 IC. I am currently facing few issues getting it to work according to my requirements. I am using an EVAL-ADXL372Z development module along with an ATSAMD21G18 microcontroller with an Arduino core to get of ADXL372. I started off with the ADXL example code mentioned here. I was able to get that… (Show more)

I have a ADXL355 EVAL wired up to the SPI B bus on my MPC565 processor board. Registers reads work fine but writes don't stick. I have verified against the datasheet with a scope (A7-A0 and R/~W in the first 8 bits). I have tried SCLK active low and data driven on leading edge as well as SCLK active high with data driven on trailing edge. Clock is… (Show more)

I am using an ADIS16480 for state estimation. I get occasional fast rotations in the sensor's quaternion and gyro output. The accelerometer output is normal. This happens even when the system is sitting completely still. Also, the EKF divergence system error flag is set quite often during nominal motions ( less than 2 g's linear and 100 dps… (Show more)

Hi all,  I am trying to read ADXL372 data register XDATA_H to ZDATA_L i.e. register address as 0x08 to 0x0D. Instead of reading some valid values i am getting 0x00.    Below is my configuration-  All registers are 0 except  0x3D  --> 0x63 0x3E  --> 0x0A 0x3F  --> 0x07    Below are the steps i am following to configure -    1. Reset the… (Show more)
