Part Number: ADS8509
Other Parts Discussed in Thread: ADS8519,

Hi team,

Customer would like to choose the following two ADCs as P2P compatible alternatives, with an input range of ± 10V. However, according to the manual, the circuit connections are inconsistent in this application. They would like to confirm if these two ADCs can be used as P2P compatible sources?

BRs

    Hao,

    Yes, both the ADS8509 and ADS8519 have the same pin-out.  There are differences from the standpoint of the internal resistive elements though and the ADS8509 needs the three additional resistors shown above for the +/-10V input range.
