This modules provides a simple way to interface the ADS1256 IC to various Micro-controllers, Arduino and even to Raspberry Pi. ADS1256 function and characteristics On-board high precision TI ADS1256IDB ADC chips On-board ADR03 2.5V datum voltage source chips Data output rates up to 30ksps, nonlinearity is low to ±0.0010％ The module can be configured as either 8 single-ended inputs or 4 differential inputs ADS1256 module is suitable for measuring analog voltage within 3V Module operating voltage is 5V Interface description 5V、GND：5V power input SCLK, DIN, DOUT, CS：SPI communication Interface DRDY：ADS1256 data be ready output (Active low level) PDWN：ADS1256 Sync / Turn off the power input (Active low level) AIN0-AIN7：Analog voltage input, it can be configured as either 8 single-ended inputs or 4 differential inputs,(The measured voltage should be shared with the module) Precautions Because the voltage of ADS1256 is 5V,and The measured voltage should be 2V below the supply voltage, so The module is only suitable for measuring analog voltages within 3V.
