High Precision ADS1256 24 Bit 8 Channel ADC Data Acquisition Board Module AD Collecting Data Acquisition Card Overview: ADS1256 8 road 24-bit ADC module mounted TI ADS1256IDB, minimum Power consumption, high precision ADC chipsand 2.5V datum voltage source, using SPI interface communication protocol, data output rates up to 30ksps, supportsingle-ended input and differential input. Feature: On-board high precision TI ADS1256IDB ADC chipsOn-board ADR03 2.5V datum voltage source chipsData output rates up to 30ksps, nonlinearity is low to ±0.0010%The module can be configured as either 8 single-ended inputs or 4 differential inputsADS1256 module is suitable for measuring analog voltage within 3VModule operating voltage is 5VThe board size is 61*35*11mm Interface description: 5V, GND: 5V power inputSCLK, DIN, DOUT, CS: SPI communication InterfaceDRDY: ADS1256data be ready output (Active low level)PDWN: ADS1256 Sync / Turn off the power input (Active low level)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. Testing Methods: Module provides STC15W and STM32 microcontroller 8-channel serial display reference program and STC89C52 single-chip4-channel 1602LCD display reference program, the STC89C52 Microcontroller + 1602 LCD LCD test method is as follows:5V, GND connect to DC 5V power supply, SCLK, DIN, DOUT, DRDY, CS connect to Microcontroller P1.2, P1.3, P1.4, P1.5, P1.6 respectively,AIN0, AIN1, AIN2, AIN3 connect to 2.5V, 2.5V, 2.5V,2.5V respectively (The measured voltage should be in common with the ADS1256),then 1602 LCD will shows these four sets of voltage values, in which, the 1st ,2nd ,4th sets are single-ended input voltage value ofAIN0, AIN1, AIN3, and the 3rd set is the difference of AIN2-AIN3, the voltage values of these four sets are 2.5V, 2.5V, 0V, 2.5V. Package included: 1 x ADS1256 24 Bit 8 Channel ADC AD Module
The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
