Part Number: INA191 Tool/software: I created the below schematic based on the datasheet from the INA191A1, but now I am wondering if it is correct to measure the ~100uA sleep current I am looking for?
Part Number: INA190-Q1 Other Parts Discussed in Thread: INA191 , INA190 Tool/software: Hi, I downloaded the PSPICE simulation models of INA190-Q1 and they do not work, they have floating nodes, is there a solution for this? Thank you very much in advance…
Part Number: LMP8646 Other Parts Discussed in Thread: INA190 , INA191 , INA186 , LM51551 , LM5121 Hi support team,
We are using the LMP8646MK/NOPB as a current-limiting circuit for the LM5155DDST boost converter to charge a supercapacitor at 165 V and…
Dear Javier,
Thank you for your support.
I checked the file you linked.
For INA191-Q1, I got results as below regarding to different gains.
I found that the device which have lower gain can use high value shunt resistor. but power at 250A rises…
Part Number: INA199 Other Parts Discussed in Thread: INA190 , INA191 , INA186 Hi team,
ASUS now want to use the INA199A3DCKR material and connect the Supply Voltage, IN+, and IN– pins to DC_IN 24V. Calculated based on a tolerance of ±5%, the voltage…
Other Parts Discussed in Thread: INA190 , INA191 , INA186 , INA2191 Hello,
I need a way to measure low current on a negative voltage -24V.
I there a way to connect a current sensing amplifier for this negative common mode.
The parts I found are…
Shinichi,
I would recommend the INA190 or INA191 . Section 8.1.2 of these datasheets has information about how to choose the optimal shunt resistor based on maximum allowable power dissipation and the maximum current.
The rest of section 8 details…
Part Number: INA317 Other Parts Discussed in Thread: LM7705 , INA190 , INA191 Hello E2E Expert,
We are looking for INA317 application to be used for low side current sense amplifier (microvolts drop across the low side shunt to be amplified )
One…
Part Number: INA199 Other Parts Discussed in Thread: INA180 , INA823 , INA181 , INA190 , INA191 , INA186 I am trying to create a bidirectional circuit for battery charge / discharge. The currents are from 0.25A to 3A. The ADC reference is 2V, system Vcc…
Part Number: TPS61391 Other Parts Discussed in Thread: TPS61390 , INA191 Hello,
My customer has the following questions about TPS61391 spec on page #5 of the datasheet.
They would like to use TPS61390 at IAPD = up to 4mA. In this case, how…
