Origin: Mainland China
Model Number: AD Module
Chip used: ADS1256IDB
Output rate: up to 30ksps with low non-linearity of ±0.0010%;
Single-ended/differential inputs: the module can be configured for 8 single-ended inputs or 4 differential inputs;
Operating voltage: 5V
5V: 5V power input
GND: input power supply negative
SCLK, DIN, DOUT, CS: SPI communication interface;
DRDY: ADS1256 data-ready output (active low);
PDWN: ADS1256 synchronous/power-down input (active low);
AIN0-AIN7: analogue voltage inputs, can be used as 8 independent single-ended inputs or 4 sets of differential inputs (measurement voltage needs to be shared with the module)
Size: 60 x 35 x10mm/2.4 x 1.4 x 0.4inch
Built-in TI\'s ADS1256 8-way 24-bit ADC module ADS1256IDB, low power consumption, high precision ADC chip and 2.5V reference voltage source, using SPI interface communication protocol, data output rate up to 30ksps, support single-ended input and differential input.
As the ADS1256 is 5V and the measured voltage should be 2V lower than the supply voltage, the module is only suitable for measuring analogue voltages up to 3V.
The module provides 8-channel serial display reference program for STC15W and STM32 microcontrollers and 4-channel 1602 LCD display reference program for STC89C52 microcontroller. The test method for STC89C52 microcontroller + 1602 LCD LCD is as follows: 5V, GND connected to DC 5V power supply, SCLK, DIN, DOUT, DRDY, CS are connected to microcontroller P1.2, P1.3, P1.4, P1.5, P1.6, AIN0, AIN1, AIN2, AIN3 are connected to 2.5V, 2.5V, 2.5V, 2.5V, 2.5V respectively (the measured voltage should be shared with ADS1256), then 1602 LCD will display these four sets of voltage values, where the second, fourth set is the single-ended input voltage AIN0, AIN1, AIN3 and the third group is the difference between AIN2 and AIN3, which are 2.5V, 2.5V, 0V and 2.5V respectively.
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
