Overview|LC ADS1256 8 road 24-bit ADC module mounted TI ADS1256IDB, minimum Power consumption, high precision ADC chips and 2.5V datum voltage source, using SPI interface communication protocol, data output rates up to 30ksps, support single-ended input and differential input.|Function features1.On-board high precision TI ADS1256IDB ADC chips|2.On-board ADR03 2.5V datum voltage source chips|3.Data output rates up to 30ksps, nonlinearity is low to ±0.0010％|4.The module can be configured as either 8 single-ended inputs or 4 differential inputs|5.ADS1256 module is suitable for measuring analog voltage within 3V|6.Module operating voltage is 5V|7.Board size: 60*35 mm|Interface description|1. 5V -GND: 5V power input|2. SCLK、DIN、DOUT、CS: SPI communication Interface|3. DRDY: ADS1256data be ready output (Active low level)|4. PDWN: ADS1256 Sync / Turn off the power input (Active low level)|5. 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.
