 		 #75441 - RE: Is it used for auto-calibration rout
Responding to: ???'s previous message
Hi Kai Klass

The signal is converted to a PWM(digitize) at very close to the sensor. As i need not tell you, i will avoid the noise very much. I am familier with 24bit delta/sigma ad7710, ads1242, cs5502 ics But not able to get more than 1 in 100000.

I've seen many systems not using 24ADC but with a PWM.
That is why i decided to try the PWM way.

could you remember about curve fitting that we were discussing, i was successful with offset/ span and linearity compensation for the precision balance 1000 grams / 10mg accuracy
