Feature: 1. The data output rate of this data acquisition card is as high as 30ksps, realizing high-speed output and strong practicability 2. ADC module can convert continuous signals in analog form into discrete signals in digital form 3. The data acquisition board is suitable for measuring analog voltages within 3V, with a non-linearity as low as ±0.0010% 4. Module can be configured as 8 single-ended inputs or 4 differential inputs to meet different needs 5. The data acquisition module adopts high‑quality PCB and ADC chip with high accuracy and high‑performance operation Specification: Item Type:Data Acquisition Module Overview: ADS1256 8-Channel 24-Bit ADC Module Equipped with TI ADS 1256IDB, Low Power Consumption, High-Accuracy ADC Chip And 2.5V Reference Voltage Source, Using SPI Interface Communication Protocol, Data Output Rate up to 30ksps, Support Single-Ended Input and Differential Input Interface Description: 5V, GND: 5V Power Input SCLK, DIN, DOUT, CS: SPI Communication Interface DRDY: ADS1256 Data in Order Output (Active Low) PDWN: ADS1256 Sync/Turn Off The Power Input (Active Low) AIN0-AIN7: Analog Voltage Input, Configurable as 8 Single-Ended Inputs or 4 Differential Input Values, (The Measured Voltage Should be Shared with The Module) The Third Group is The Difference Between AIN2-AIN3, Which are 2.5V, 2.5V, 0V, and 2.5V for The Four Groups. Package List: 1 x Module Note: Since the voltage of ADS1256 is 5V, the measured voltage should be lower than the power supply voltage 2V, so this module is only suitable for measuring analog voltages within 3V.
