ADS1015: Monitor input voltage with resistor divider circuit

Part Number: ADS1015

Hello team,

 

Customer will monitor the input voltage with resistor divider circuit.

Are there any concern on the above ?

 

Thank you and best regards,

Michiaki

  • Hello,

    There aren't fundamental concerns when monitoring a resistor divider input with the ADS1015. Just make sure the divided voltage is within the input and supply range of the ADC.

    The non-zero input impedance will be in parallel with the bottom leg resistor of the divider and will result in a small gain error.  The smaller the bottom resistor is, the smaller the gain error will be.
