Overview:
ADS1256 8 road 24-bit ADC module mounted TI ADS1256IDB, minimum Power consumption, high precision ADC chips
and 2.5V datum voltage source, using SPI interface communication protocol, data output rates up to 30ksps, support
single-ended input and differential input.
Feature:
On-board high precision TI ADS1256IDB ADC chips
On-board ADR03 2.5V datum voltage source chips
Data 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 inputs
ADS1256 module is suitable for measuring analog voltage within 3V
Module operating voltage is 5V
The board size is 61*35*11mm
Interface description:
5V, GND: 5V power input
SCLK, DIN, DOUT, CS: SPI communication Interface
DRDY: 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-chip
4-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 of
AIN0, 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.
