TMS320F28027F: Internal temperature sensor reading more

Raghuchandar Rajula

Part Number: TMS320F28027F
Other Parts Discussed in Thread: LAUNCHXL-F28027F, CONTROLSUITE

Hi all,

I am using LAUNCHXL-F28027F. The internal temperature sensor routed to ADCINA5, is reading 120degC @ room temperature of 25degC. The offset and gain follows.

Gain = 5629 (in Q15 format) & 0.1717834 (in float)

Offset = 1692 (ADC Counts)

Please help.

Hi Raghu,

Did you go thorough this example code: C:\ti\controlSUITE\device_support\f2802x\v230\f2802x_examples_structs\adc_temp_sensor_conv

Gautam

Raghu,

are you still having issues?

How did you get the gain and offset readings?

Are you using internal or external references for the ADC?

Regards,
Cody
