Overview

The accelerometer features a maximum current consumption of 22 micro-amps and incorporates full power and signal conditioning.  The model 834M1 is available in ±2000g to ±6000g ranges and provides a flat frequency response up to greater than 6kHz. The standard model 834 offers the same envelope with a lower maximum current consumption of 4 micro-amps.

FAQ

Frequently Asked Questions

Question: The model 832 and 834 datasheets show the operating temperature from -40°C to +125°C. The lower limit of -40°C is not low enough; we need to measure down to -55°C. What is your recommendation for meeting this requirement?

Answer: We tested the bias at -55°C. Test result of 832-0500 DC bias change with temperature is shown below, DC Bias changes about 0.5% at -55ºC compared to 25ºC:

  25ºC -55ºC
X 1.7423 V 1.7535 V
Y 1.7412 V 1.7477 V
Z 1.7928 V 1.8035 V

Total current supply is 4.1uA at -55ºC which is still within specification. However, for continuous usage down to temperature of -55°C, the model 832M1 and 834M1 are recommended.

 

Question: Do you happen to have any more detail for the assembling the model 832 and 834 to a board? Our board assembly department is a little concerned about manually soldering this part. It says on your data sheet that the accelerometer can’t go through solder reflow at high temperature and that manual soldering is recommended. I was hoping for some more clarification on this statement.
