About This Product

The AD7190CM is a 2ch differential input AD conversion board that uses a 24bit sigma delta AD conversion IC with a built-in variable gain amplifier. Measured values ​​can be read out in binary or voltage values ​​using communication commands.

■Circuit

-The entire circuit operates on USB bus power. No external power supply required. -The AD conversion circuit including the AD7190 and the USB side circuit including the CPU are isolated. ・It has 2 channels of differential input: CH0= (Ain0-Ain1) and CH1= (Ain2-Ain3). ・The differential input voltage range for CH0 and CH1 is ±2.5V/Gain. ・Gain can be set to 1, 8, 16, 32, 64, 128. ・The absolute value of the input voltage of each input terminal of CH0 and CH1 is 250mV to 4.75V (input buffer on) or -50mV to +5.05V (input buffer off) with CN1 pin 6 (GND) as the reference potential. limited to range.
