Description:

The High Precision ADS1256 24 Bit 8 Channel ADC Data Acquisition Board Module is a highly accurate and efficient device for collecting and measuring analog voltage data. It features a TI ADS1256IDB ADC chip for minimal power consumption and high precision, and an ADR03 2.5V reference voltage source chip. With data output rates of up to 30ksps, the module supports both single-ended and differential inputs and has a nonlinearity of ±0.0010%. It can be configured as 8 single-ended inputs or 4 differential inputs and is suitable for measuring analog voltages within 3V. The module operates on a 5V power supply and has a compact size of 61x35x11mm. It uses an SPI communication protocol and has a DRDY output for data readiness. It also has a PDWN input for power synchronization and AIN0-AIN7 inputs for analog voltage measurement. The module comes with reference programs for STC15W and STM32 microcontrollers and can be tested using an STC89C52 microcontroller and 1602 LCD. It should be noted that the measured voltage should be shared with the module and should be 2V below the supply voltage.
