High-Precision AD HAT for Raspberry Pi, ADS1263 10-ch 32-bit ADC,compatible with Raspberry Pi series and Jetson Nano
Raspberry Pi GPIO interface does not have AD function, if you want to use high-precision AD,Then i will be a good choice

Features
Adopts ADS1263 chip, low noise, low temperature drift, 10-ch 32-bit high precision ADC (5-ch differential input), 38.4kSPS Max sampling rate
with embedded 24-bit auxiliary ADC, internal ADC test signal, IDAC, 2.5V internal reference voltage, 8x multiplexing GPIO, PGA (32 times Max)
Onboard AD header input, compatible with Waveshare sensor pinout, for connecting sorts of sensor modules
Onboard AD screw terminal input, allows connecting analog signal and analog power supply, general purpose interface
Onboard control header, make it easy to control the module by other hosts in additional to Raspberry Pi
Three-wire RTD (resistor temperature detector) circuit, enabled by soldering 0R resistor
