ADS1256 8-channel 24-bit module is equipped with TI ADS1256IDB -power consumption, high-precision chip and 2.5V reference voltage source, SPI interface communication, data output rate up to 30ksps, supports single-ended and differential input. Product Parameter: Use chip: ADS1256IDB Output rate: up to 30ksps, low nonlinearity is 0.0010% Single-ended / differential input: the module can be configured as 8 single-ended inputs or 4 differential inputs : PC+Metal Color as shown Working voltage: 5V 5V: 5V power input GND: input power negative SCLK, DIN, DOUT, : SPI communication interface DRDY: ADS1256 data output (active low) PDWN: ADS1256 sync / power off input (active low) AIN0-AIN7: Analog voltage input terminal, which can be used as 8 single-ended inputs or 4 sets of differential inputs (the measured voltage should be shared with the module). Note: Since the power supply voltage of ADS1256 is 5V, and the measured voltage should be 2V lower than the power supply voltage, the module is only suitable for measuring analog voltages within 3V. Package Contents: 1 x AD acquisition module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
