On-board high precision TI ADS1256IDB ADC chips and 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 The board size is 35*60mm
Specifications : 5V, GND: 5V power input SCLK, DIN, DOUT, CS: SPI communication Interface DRDY: ADS1256data 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)
* 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.
