ADS8867: Alternative ADC with Bipolar, Differential Input Range

Part Number: ADS8867
Other Parts Discussed in Thread: ADS8317

Tool/software:

Hello everyone,

I have found the ADS8867 because it almost perfectly meets the requirements that I have, save for the bipolar input range. Is anyone aware of another IC that supports bipolar inputs and also meets my other requirements? I'm grateful for any hints or advice. Basically the ADS8867 would be perfect for my application if it had a bipolar input range.

My requirements are:

  • 1 channel
  • +-2 V bipolar input range
  • Differential input
  • Ideally 16bit resolution or higher
  • Can run on +-3V supply (battery)
  • At least 100kSps
  • Straightforward serial interfacing (SPI or SPI compatible like the ADS8867)

Thank you in advance and have a nice day

- Daniel

  • Hi Daniel,

    Thanks for your question! Looking around, perhaps the ADS8317 would be a good fit. Let me know if it doesn’t meet your needs and I can offer some other alternatives as well.

    Best regards,
