CJMCU-1220 ADS1220 24-Bit ADC Module (SPI Low Power Analog-to-Digital Converter)

The CJMCU-1220 ADS1220 ADC Module is a high-precision 24-bit analog-to-digital converter (ADC) designed for low-power, high-resolution signal acquisition. Based on the Texas Instruments ADS1220 ADC, the module supports both differential and single-ended analog inputs, making it ideal for accurately measuring low-level sensor signals in industrial, scientific, and embedded applications.

The module communicates through a SPI interface and features an integrated programmable gain amplifier (PGA), low-noise architecture, and support for both internal and external voltage references. It is compatible with Arduino, ESP32, STM32, Raspberry Pi, and other SPI-enabled microcontroller platforms for precision measurement and data acquisition.
