Part Number: OPA313 Hello,
We have used the OPA313IDCKR part in one of our designs. We facing one issue regarding the device/ top marking of this IC. We have checked the datasheet of the IC, but there are mentioned two different device markings of OPA313IDCKR…
Part Number: OPA313 Dear TI-san,
I decided to use a microphone"A" with an output impedance of 5.2kΩ and set resistance of the amplifier input to 3.6kΩ.
3.6kΩ is intended to minimize power supply noise of connected laptop computer…

Low-side, bidirectional current-sensing circuit | TI.com Video
In this training video, I feel confused about the reason to choose Vshunt maximum as 100mV, and also confused about…
Dear Michallick-san,
Thank you reply.
I know that hum noise can be reduced by adding "Auto Gain Control" or "Commander".
However, hum noise level is not constant.
So I don't think signal processing including your suggestions can…
Part Number: OPA313 Hi Team,
My cusromer has a request on current sensing, full load range is ±40A, and the sensing accuracy error needs to be below 1% when the load is within ±5A(light load).
Besides, customer needs bidirectional input and…
Part Number: OPA313 Other Parts Discussed in Thread: OPA316 , OPA314 , , TINA-TI Current issue is that I am comparing some circuits using OPA313, OPA314, and OPA316 pspice models. If I simulate identical circuits using OPA313 and OPA314 in the same schematic…
Part Number: OPA313
Hi there.
The attachements are given by TI's engineer's cookbook : Amplifier (p57, Low-side, bidirectional current sensing circuit).
I don't exactly understand why Vref is needed.
It's relevant with the issue of my customer…
Part Number: OPA313 In the datasheet for this OPA313 on page 2 the OPA313 (SOT23-5) DBV package has a package marking as "SIF" but on page 21 this OPA313IDBVT (SOT-23) shows deice marking as "SIF". The part (OPA313IDBVT) we received…
Part Number: OPA313 Hello,
I was wondering what the best way to test the stability of this circuit is since the feedback involves a FET? Would it be best to use the standard method talked about in precision labs or the transient overshoot method? How…
