  • Low noise and low temperature drift from ADS1263 chip ensure stable, accurate readings
  • Built-in 24-bit auxiliary ADC plus internal test signal simplifies calibration and diagnostics
  • Programmable gain amplifier up to 32× boosts weak signals without external circuitry
  • Differential and single-ended inputs with internal 2.5 V reference support versatile sensor connections

Precision data acquisition

The WaveShare ADS1263 HAT adds a 10-channel 32-bit delta-sigma ADC to Raspberry Pi 4B, 3B+, 3B, 2B, Zero variants and Jetson Nano. It targets engineers and hobbyists who need laboratory-grade analogue capture directly on the GPIO header.

Low thermal footprint

The ADS1263 chip is specified for low temperature drift and low noise, drawing minimal current from the host supply. No active cooling is required and the board adds negligible acoustic load to a silent Pi deployment.

Flexible analogue front-end

Onboard screw terminals and a pin-header matched to WaveShare sensor modules let you connect raw signals or powered sensors without adapters. An embedded 24-bit auxiliary ADC, internal test signal, IDAC sources and 2.5 V reference simplify calibration, while eight multiplexed GPIOs and a programmable gain amplifier up to 32× extend digital control.

Questions about this item

How do I install the ADS1263 HAT on a Raspberry Pi and which step is most often missed?

Align the 40-pin header with the Pi's GPIO, press firmly until seated, then enable SPI in raspi-config; the step most often missed is enabling SPI before running any code.

What maintenance or replacement will the ADS1263 HAT need over time?

The board has no moving parts or consumables; the only likely replacement is the screw-terminal blocks if wiring is changed repeatedly, and the 0R resistor for RTD use must be soldered once if that feature is required.

What limit appears first when running the ADS1263 at its maximum 38.4 kSPS continuously?

The 38.4 kSPS sampling ceiling is the first hard limit; the 32× PGA and 2.5 V internal reference remain available, but the converter cannot exceed the stated maximum sample rate.
