Re: AD22151 Output Voltage Range

Hi Kris

I have a bipolar configuration, with R2 open circuit and R3 short circuit to obtain a sensitivity of 0.4 mV/G. The sensor output is connected to two 16 K resistors in parallel, one connected to 2.22 V, and the other connected to 2.1 V. In this configuration, my output voltage range is limited from 1 V to 4 V. At a measured output of 4 V, my output current is calculated as 0.23 mA. At a measured output of 1 V, my output current is calculated as -0.15 mA

When I remove the 16 K resistors, and thus have no output current, my sensor range is from 0.5 to 4.5 V.

Thanks for looking into it.
