ADS12568 24-Bit Adc Module ADS12568 -Channel 24-Bit Adc Module Equipped With TIADS1256IDB Micro-Power Consumption, High Accuracy ADC Chip And 2.5v Reference Voltage Source, Using Spi Interface Communication Protocol, The Data Output Rate Can Reach 30ksps. Supports Single-Ended Input And Differential Input. Description: 1. On-board chip: on-board high- TIADS1256IDB ADC chip and ADR0325V power supply reference chip 2. data output rate: data output rate can reach 30ksps, low non-linearity of ± 0.0010% 3. single-ended / differential inputs: the module can be configured as 8-way single-ended inputs or 4-way differential inputs 4. Measurement of analog voltage: suitable for measuring analog voltage within 3V 5. operating voltage: 5V Test method: The module provides STC15W&&STM32 MCU 8-channel serial port display reference program and STC89C52 MCU 4-channel 1602_LCD display reference program, of which STC89C52 MCU+1602LCD liquid crystal simple test method is as follows: 5V, GND connected to the DC5V power supply, SCLK, DIN, DOUT, DRDY, were connected to the microcontroller's P1.2, P1.3, P1.4, P1.5, P1.6, AINO, AIN1, AIN2, AIN3 were connected to the 2.5V, 2.5V, 2.5V, 2.5V (the measured voltage should be and ADS1256 common ground). The 1602 LCD display 4 groups of voltage values, of which groups 1, 2 and 4 are single-ended input voltage values of AIN0, AIN1 and AIN3, and group 3 is the difference between AIN2 and AIN3. The 4 groups of voltage values are about 2.5V, 2.5V, 0V, 2.5V respectively. Note: Different Batches May Have Differences In Product Appearance, Color, And Printed Characters, Which Not Affect The Use size: About 60 x 35mm Material: PCB colour: dark blue Package Contents: 1 x ADS12568 Channel 24-Bit ADC Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
