Adding 22nF feedback should be fine and eliminates the need for R1. You do not show how you derive Vref but if it is a buffered reference voltage or series reference voltage, it is actually advisable to use it to drive both nodes, non-inverting input…
I am working on digital stethoscope and want to design pre amplifier and Low pass filter can any one suggest any good technical documents on how to design pre amplifier and Low pass filter.
It will be a great help.
Thank you
Part Number: OPA335 I haven't determined the lot cod yet, I have a reel with date code: 1951 +5 and another reel with date code 1929.
We have a good number of boards failing. changing chip fixes half of them.
The part runs on a +5 V rail unity gain…
Part Number: OPA335 Hi,
based on reference design SBOM746B.TSC I created an TINA schematic.
Starting the Oscilloscope, I get an error message.
Please see the picture, all Information is shown there.
How can I solve this problem?
Greetings,
Steffen
Part Number: OPA335 hi dear supporting team,
customer using OPA335 with below circuit: using it sense the battery current with a shunt resistor of 25 mOhm. sometimes when the battery is shorted, the current will be several hundreds mA, the voltage at…

Part Number: OPA335 Other Parts Discussed in Thread: TINA-TI Tool/software: TINA-TI or Spice Models Hi Sir
I am not similar TINA software, May we check if TINA(or webench) can simulation as below condition?(or have vedio can teach)
1. K-type (0C) = 0mV…
Part Number: OPA335 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hi Sir
I have use OPA335 in TINA simulate as below:
The VP_3 should be around 0.014V. but TINA is show 2.49V.is some thing wrong here?
