ADS1256 24-bit 8-channel ADC AD module high-precision ADC acquisition data acquisition card -73757
product detail
ADS1256 8-channel 24-bit ADC module is equipped with TI ADS1256IDB micro power consumption, high-precision ADC 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;
Working voltage: 5V
5V: 5V power input
GND: input power negative
SCLK, DIN, DOUT, CS: SPI communication interface;
DRDY: ADS1256 data ready output (active low);
PDWN: ADS1256 sync / power off input (active low);
AIN0-AIN7: Analog voltage input terminal, which can be used as 8 independent 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.
