High-Precision AD HAT For Raspberry Pi, ADS1263 10-Ch 32-Bit ADC

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, 8 x 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 addition to Raspberry Pi.
• Three-wire RTD (resistor temperature detector) circuit, enabled by soldering 0R resistor.
