ADS8688: Digital Input to ADC

Part Number: ADS8688


Hi,

We are planning to implement Multilevel thersholding using ADC, whereas my input will be in DC voltage from the rf detector, so will my ADC accept DC voltage and provide the sampling data?

 

RF detector (Vout of Rf detector is DC from the range of 0.22 to 1.4VDC based on the RF power the voltage will change we need to monitor the voltage level) 

Vout of RF detector is connected to input of AD8688. 

Kindly let us know the possibility of using same part or suggest alternate parts.

 

 

 

 

 

  • Hi Bharath Kumar,

    ADS8688 can definitely provide the sampling data if your signal is a single-ended 0.22 to 1.4V DC signal, but I would recommend you to use ADS8688A which has an input range of 2.56V so that you can use the full scale dynamic range as much as possible.

    BR,
