TMS320F28069: The input circuits for analog ADC input channel.

Part Number: TMS320F28069
Other Parts Discussed in Thread: ADS8319


Hi Team,

My customers want to use TMS320F28069 internal ADC for current signal sampling, however they need to decrease the voltage which is the output from the filter AMP by divided resistors before it connects to the ADC input. Then the input signal voltage range will be falls in the power range of 28069. 

Could you please help to show some guidance with the divided resistors value? These values shall not affect the internal input impedance.

Best regards
