  • ADS1232: Reading onboard Temperature Sensor

    TI Thinks Resolved
    Part Number: ADS1232 Tool/software: The issue seems to persist. The ADC generates a value of 415922, corresponding to a Voltage of 123mV (ADCout/ADC_MAX)*(Vref/2) This would mean the chiptemp is at 25°C + ((123mV-111.7mV)/379uV/°C) = 56°C which is unreasonable…
