Part Number: LM2904 Other Parts Discussed in Thread: LMV358A , LM358LV , , , In a sensor project (low cost instrumentation amplifier for pressure sensor in wheatstone bridge configuration) we are using LM2904DGKR but on a batch marked 23TI we had a suspected…
Hey Song,
Check the current at the output of the amplifier, and through your feedback resistor. You will see as this value increases past a certain uA range (as Ron mentioned above), you will no longer be able to drive the output low enough to properly…
Part Number: LM2904 In our system LM2904D is used and it is shown Obsolete as per silicon expert. Exact, This PN is not shown in datasheet PN list. LM2904DR is Active. so, Can we replace it with LM2904DR? What is difference between 'D' and 'DR'?…
Part Number: LM2904-Q1 Other Parts Discussed in Thread: LM2904B-Q1 Hi team,
I use LM2904-Q1 for small signal amplification.During the test, it was found that LM2904-Q1 did not meet the requirements of virtual short. TI's technical support staff told me…
Hi Marian,
as Ron answered, yes, the output should go high then, as explained in the datasheet. But keep in mind that the performance of LM2904 (refering to speed, etc.) will be degraded when leaving the common mode input voltage range.

Hi Ron:
Customers say PIN2 has no negative voltage.
This picture only shows the difference between t he 2221 and 2144 batches LM2904
Customer found some problems between 2 batches and then do some experiment
The picture show that customer test 3-pin (IN…
Part Number: LM2904 Hi
I am using LM2904 IC as Non inverting opamp to increase the range. Op amp input voltage range is 1.44V to 2V and output should vary from 0 to 3.2 V to supply to micro. The Vdd of the opamp is 5V. How to select the resistor values…
Part Number: LM2904 Hi Team, In the original post, Ron mentioned that the LM2904QDR part is a "step up" commercial device compared to LM2904DR. Can we ask for the specific meaning of this statement? Is it in terms of an added screening/qualification…
Hi Cherry,
Is there any updates with the questions or additional information the customer can provide? In the meantime, I will set my answer as "TI Thinks Resolved" but please feel free to add to this thread or contact us with any questions.…
Part Number: LM2904B-Q1 Hi team,
My customer is using LM2904B-Q1 in their design with single rail power supply. The minimum output from calculation is to 1.6V,
They found the output variation respect to ideal result is much larger at -40C compared with…
