Hi

How is the "Null adjustment" method as it mentioned in ADXRS623 datasheet that include injecting current to SUMJ?

Can you give me an example please?

i need to increase RATE OUT NULL from 2.488 to 2.553.

Can you write the calculation ?

I just used 2.6k resistor between SUMJ and Rate Out to fixe this Voltage. but it doesn't response matching with Scale Factor(12.5mv per deg/sec). i think maybe i just reduced the BW too much.

thanks a lot

The SUMJ node has the rate output as a current signal, which is converted to voltage by the total output resistance Rout. To adjust the offset voltage by X volts, a current = X/Rout has to be injected in to SUMJ.
