Part Number: INA284 Other Parts Discussed in Thread: INA190 Hi team,
Will this chip divert part of the current from the main circuit when collecting voltage?because my main current is very small, ma level.
My current to be measured is very small,…
Part Number: INA284-Q1 Other Parts Discussed in Thread: TMCS1100 , TMCS1101 , INA139 , INA284 TI Bidirectional current sense common-mode voltage range is up to 85V.
Our customer is looking for solution of 100V bidirectional high side current sense…
Hi Martin,
The input filtering needs to be modified. If you want to add input filtering to the device you need to add resistors in series with each input. Try connecting 10ohm resistors on BOTH IN+ and IN-. I am not sure what noise are you trying to…
Hi hu shuanglu,
What is the source of AM3 in your circuit? I guess if AM3 is increased to mA range, then AM3 and AM1 will become almost equal. Typical value of Input bias current for your INA284 is 25uA.
But supply voltage that sources AM3 must…
BP101 said: So the full wave DC supply (above post) introduces AC ripple
Might a high-value capacitor be (usually) required to create a, "DC supply?" No cap is in evidence w/in poster's hand-drawing. (below)
The output at the diode junction would…
Hi,
Hope you are having a great evening.
1. The datasheet update was done in May 2015 (9 months ago - not 4 years). Attached are the two versions. Version B (Revised 2012 - still include App information). Version C (Revised May 2015 Current version…
Anish,
Check out the INA282 family. Depending on the gain you need and the speed of the signal, it could well work for you. What kind of accuracy are you looking for?
I'm out on business travel for the week so Rabab Itarsiwala will be able to help…
Sho,
There are more sources of offset error than those you listed; see pages 21-22 in the data sheet. The term you are missing is likely the Rcmr term, which is responsible for the offset contributed to the error when the VREF isn't 2.048V. In the TINA…
