- the__alchemist 6y agoI can post the design if you'd like, although it's easy to tell from the datasheet, which lists the main parts. It uses a pair of AD8603 op amps feeding the differential input of a TI ADS1115 ADC. The intent is to use the op amps in a unity gain config, to deal with the probe's high impedance.
