Other Parts Discussed in Thread: ADS1263, ADCPRO
Dear All,
I got in my lab ads1263 demonstration kit and would like to sample data from two acceleration sensors simultanously for a calibration purpose. One sensor provides a DC voltage using a BNC connection from a piezosensor. The piezosensor is connected to an amplifier which is connected to the ADC (here is the link for the amplifier model 442A101 for more details). The other sensor is a MEMS sensor (ADXL354). I know that the ADC gives a ratiometric measurement which means I need a reference voltage for each measurement. For the MEMS sensor, it has a pin which I can use as a reference voltage. I don't know how to overcome this requirement for the other sensor (my first attempt is to just measure the voltage using a multimeter simultaneously until I find a good value for the internal reference voltage of the ADC, however, the magnitude of the sensor voltage differs from mV to V regime and I guess this might influence the accuracy of the measurement). )
