Part Number: INA212 I want to use the INA212 to sense current over a resistor. However, I would like to power it with +5V and -5V, and not +5V and GND. The reason for this is that I would also be able to sense AC current through the resistor. I have simulate…
Part Number: INA212-Q1 Dear all,
Could you teach me how to decrease current consumption?
I consider about the current consumption when system is off.
Best regards,
Hi Takao,
this would destroy the INA212 as well, if its supply voltage is smaller than 12V! But why should there be a short circuit between these two pins?
The usual method to protect the following ciruitry against overvoltage is to use a zener…
Part Number: INA212 Hello,
I have designed a test set-up to monitor the current draw from multiple devices for a period of time.The INA212 is in parallel with an 18V supply to the device and powered from a separate 5V supply. Circuit below.
I…
Hi Nikita,
I am sorry to hear you are experiencing difficulties with the circuit. Based upon your description of the problem I think there must be a high voltage applied to the INA212 and we will need to check it. Before I make my observations to you…
Pete;
To verify that this was not a bandwidth problem, I replaced your DC curent source woth a square wave current generator set to +/-20mA @ 1kHz.
My results were the same as yours-- the circuit works just fine.
Hi Tim,
I've been using the INA214 in my current sense circuit, directly connected to the input of a UCD90120A power sequencer (not shown). The INA214 has an input filter where Rfilt=100R and according to the currently released datasheet (as of today…
Other Parts Discussed in Thread: INA212 hello,
I want to make short circuit protector with shunt monitor INA212. I make square wave current ,where impulse voltage is 12volts, impulse width 2ms. period from 7ms to 30ms. voltage that drops to shunt is…
Part Number: INA186-Q1 Other Parts Discussed in Thread: INA212 Tool/software: Hi expert,
My customer want to use a Current-Sense Amplifier to trigger 3.0A current with a 0.2mΩ shunt resistor, and they thought the gain is not enough. Do we have more…
