Part Number: INA225 Other Parts Discussed in Thread: LM324 Tool/software: Hi,
I am working on Insulation Resistance Tester using INA225.
My measurement range is 0 to 2000 M ohm and Voltage is 1000 VDC.
I am facing an issue it is not working properly…
Hello Purvik,
The issue is what everything is referenced to and when there is isolation that the devices meet the requirements for voltage. For example the schematic has 3 different GND and each one is referenced to a different node. The GND1 is the reference…
Part Number: INA225 When used at low temperatures below -20℃, it may take several seconds for the output voltage to stabilize. It seems that it will continue to output 5V until the output stabilizes. The supply voltage to INA225 is 5V. Do you know if this…
Hi Thomas,
I tested your conditions with our EVM which has the following schematic.
In all of my tests I could confirm a gain of 100V/V at the output for different currents/Vshunt values through Rsense.
It was done with constant DC currents through Rsense…
Hello Sandip,
My apologies delay. I was hoping to get the actual pspice circuit project files so I could try running the simulation and debugging the netlists.
For the LTSpice, I will assume the INA225 (U5) does not appear to be generating error, but I…
Part Number: INA225-Q1 Other Parts Discussed in Thread: INA225 , Can I replace ina225-q1 with the ina225 when aplication is industrial..
Is spec. Different or only quality level.
Part Number: INA225 Hello Team,
Customer is using INA225 current sense amplifier in one of the design and requested support in clarifying below point.
Issue: Need to set the gain of 100V/V by design. But observing more than 300V/V gain in practical.
…
Part Number: INA225 The resistance value calculation in the figure below shows that the minimum GAIN of the component INA225 is 20 (500K/25K=20) when the switch is OPEN, but the component GAIN is 25 times, which does not match the component specifications…
Part Number: INA225-Q1 Other Parts Discussed in Thread: INA225 , Hello team,
Are there any p2p alternatives to INA225-Q1 or INA225? I could not find any
