The Great Search — 24-bit I2C ADC Chip for RTD sensors
Published 6 months, 2 weeks ago
Description
This week we got a request on the forums (https://forums.adafruit.com/viewtopic.php?t=219635) for a way to read PT100/PT1000 RTD sensors over I2C.
To be honest, we only really stock the MAX31865 (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/MAX31865ATP/3681476) which is SPI only.
Let's find a chip that could do RTD reads over I2C: that would require 24-bit precision, but not necessarily high speed! Also ideally it could do differential reads.
