  LM94022: about supply current

  TI Thinks Resolved

  Part Number: LM94022 Hello E2E, When observed the supply current for LM94022, the supply current is to be rise to near 100mA peak, that width is about 40usec. Also, that peak current occure 2Hz. Does TI know the cause? Please give me advice. Best...

  RE: ADS112U04: ADS112U04 : reads low thermocouple voltage

  Thanks Bob. I just got to know the microcontroller which I'm using operates in the –40 to +105 °C temperature range, so now it doesn't matter how ADS112U04/LM94022 behaves below -40°C as micro functioning is not guaranteed at this...

  RE: EK-TM4C1294XL: External GPIO pull downs on PWM pins

  Bob Crosby It is more likely that the load switched by the PWM will affect the ADC. I partially agree but don't see much sample change after x6 drives PWM are running, only on start up as described below. Also occurs to me (now) there are two battle...

  RE: ADC full scale trigger source PWM0/GPTM

  Hi Bob, Backing up to the EKXL/EVM again indicates HWREG POP's even by Tivaware from ADC0/1 SS1/SS2 were often noise related (no motor). The top capture results are not of the actual channel conversions as shown below. Further by not draining FIFO2...
