  • OPA837: TIA needs protection

    Part Number: OPA837 Other Parts Discussed in Thread: TINA-TI , OPA855 Tool/software: Dear, We are designing a TIA with OPA837 but the IC is damaged after a half hour operation. We included BAT54S diodes at the input and they seem to protect the IC,…

  • OPA837: Supply pin decoupling capacitors

    TI Thinks Resolved
    Part Number: OPA837 Hello, Normally for opamps supply voltages, it is suggested that there should be (100 nF + 2-10 uF) on the positive and negative supply pins. The second capacitor which is in range of uF should tantalum ? or X7R is fine? …

  • OPA837: Low amplification in comparison to my simulation results

    Part Number: OPA837 Other Parts Discussed in Thread: TINA-TI Tool/software: Dear Engineers, I designed a transimpedance amplifier by OPA837 as follows: The negative input of OPA837 is connected to a ultrasound transducer, which is a current source…
