Part Number: TIPD104 Other Parts Discussed in Thread: LOG114
Customer is asking if we have solution to measure the current with 100nA or less. The application is to sensing the leakage current in between the special materials.
If we have total solution…
Other Parts Discussed in Thread: INA190 , INA186 , INA240 , TIPD104 , INA326 , TIPD135 , PGA281 Hi,
I am looking for a current sensing amplifier design. TI found many solutions on the TI website. These are my requirement ,
Operating Voltage: 3.3V…
Hello Awal,
You could look at the INA210. You will want a device with the lowest input offset (Vos) as possible. You can also refer to one of these designs as well for more ideas.
TIPD135 - 10uA-100mA, 0.05% Error, High-Side Current Sensing Solution…
Hi Ismail,
My appologies - I mis-read your initial post. You wrote micro amps but I read milli amps. As Gerhard suggested, you need some gain. The shunt resistor used with the AMC1200 would ideally be sub-ohms. Large shunts will cause offset and gain…
Hello Jose,
We do not have an evaluation board for the INA110. Here are 2 TI designs that might be useful for current shunt monitoring.

One other possible solution would also be…
Hello Mayer,
Concerning your question about additional current sensing reference designs, TIPD104 is a simulation-based reference design for low-side sensing from 10uA to 10mA. Both documents go through the design process step-by-step, so you should…
Hello Rahul,
It sounds to me like your common-mode voltage is "...4 to 5V" and your supply voltage is 5V. Therefore you could use the INA326 in this scenario because the input common-mode range of the INA326 can exceed the positive supply voltage by…
