Description

The project presented here can be used in isolated voltage-sensing measurement applications. The board was built using ISO224B isolated amplifier, isolated 5V DC-DC converter provides 5V DC to the input side of ISO224 amplifier, TLV6001 op-circuit converts the differential signal of ISO224 and provides single-ended output. The circuit measures the 250V AC voltage and outputs a 5V signal, the output is optically isolated and the output voltage will change proportional to the input voltage. The operating supply of the project is a single 5V DC. The divider resistor reduces the voltage from AC 250V to +/-7.5V which is within the input range of ISO224 (+/-12V). The circuit can be used to measure the DC voltage as well AC voltage.
