Description

1. The product should be wide, the product has high energy efficiency, long life and low power consumption.

2. Safe, energy saving and durable.

3. 100% quality.

4. Voltage converter signal level

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:

Module operating voltage is 5V

The board size is 35*60mm

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 shoul
