Schematic Review

Question

Hi ADI team,
Can you please review the schematic attached below for the accelerometer with I2C configuration. And also is there any sample available for EVAL-ADXL382-2Z?

Thanks & Regards

Hi Jayakeerthana, thanks for reaching out. The biggest issue I see with this schematic is that the SCL and SDA lines are flipped; SCL should go to pin 2 on the chip and SDA to pin 3. Also, it's important to keep in mind that pulling both ASEL pins to high as you've done will change the I2C device address to 0x55: There should be no problems with this but it's important that you use this value in I2C communications. Lastly, the isolating caps going to VS/VDDIO should be placed as close as possible to the chip, but are not required for proper use. 
 As for your last question, we are in the process of manufacturing a new batch of 382-2Z boards. I am not sure of the expected finish time for these boards, but I will update you if I get an exact answer. Regards, Nico)
