SKU CH-BPQD-ZA1SC

Low-power 24-bit ADC sensor module with SPI interface operating from 2.3 to 5.5V

  • 24-bit resolution captures fine signal detail
  • SPI interface enables simple microcontroller connection
  • 3 to 5.5 V supply range suits many logic levels
  • Ultra-low noise design improves measurement accuracy

ADS1220 24-bit ADC module

The ADS1220 is a low-power, 24-bit analog-to-digital converter that communicates over SPI. It operates from a 2.3 to 5.5V supply and provides ultra-low noise performance for precision sensor measurements. This module suits engineers adding high-resolution data acquisition to embedded systems.

Ideal for battery-powered instruments

Designers needing many simultaneous channels or a parallel interface will need a different converter. Buyers who require built-in signal conditioning beyond the ADC core should look at other modules. Those without SPI capability on their host controller cannot use this device.

Questions about this item

What microcontroller voltage range is required to power the ADS1220 module?

The module operates from 2.3 to 5.5 V, so any MCU or regulator within that range can supply it directly.

Can the ADS1220 share an SPI bus with 5 V legacy peripherals?

Yes, the 5.5 V upper limit lets it sit on the same SPI lines as 5 V devices without level shifting.
