Is it possible to configure the ADC to be uni-polar?

Post by jialunluo » Wed Jan 04, 2017 5:13 am

Hi all,

I am curious whether it is possible to reconfigure the ADC on the board to be uni-polar, so it uses, say, 0-1V as the full range instead of +-1V. If so, does it require any soldering? Or can I make some changes in the constraint file to reconnect some pins to make this happen?

Thank you,
Jialun

Hello,

I don't see how you could achieve this without any soldering.
You would at least need to connect the SENSE pin of the LTC2145-14 ADC to VDD instead of GND (page 15 http://cds.linear.com/docs/en/datasheet/21454314fa.pdf) in order to change the input range from +/-1 V to +/-0.5 V.
