  • RE: TLV3404: Piezo element // 2 stage op-amp design

    Resolved
    Hi Jeroen, why not taking the OPA348? The TLC272 should also work for a first testing. This is a CMOS OPAmp with low input bias current, too. Kai

  • RE: TLC2264: TLC2264 getting damaged repeatedly, could it be an ESD issue?

    Resolved
    Hi Brian, that problem do you have with any other CMOS-OPAmp as well and from any other manufacturer. The datasheet of TLC272 contains a useful information: "Because CMOS devices are susceptible to latch-up due to their inherent parasitic thyristors…

  • RE: Full bridge high power converter

    Hello, Thanks for your prompt reply. I use TI part number : UCC2895, UCC27324, TLC272, TLC393 . . . These are waveforms : Vmain_trafo = primary voltage waveform Vsec_trafo I = secondary voltage waveform (measured direct to the secondary winding) …

  • RE: TLC272C and TLC2272C in voltage follower circuit

    Resolved
    Hello Ken, The TLC272 and TLC2272 operational amplifiers are similar in their amplifier circuit design, but do have different input ESD structures. I recently checked the TLC272 on the bench and it does not have an ESD protection diode to the V+ rail.…

  • changing the Vcc supply

    Resolved
    Other Parts Discussed in Thread: TLC272 I am using the tlc272 for offset and amplification purpose. at 1st i am using 5v, the signal is linear. but after i change the vcc to 10v, the signal not longer linear. help and advice needed.

  • output impedance of instrumentation amplifier

    Other Parts Discussed in Thread: TLC272 i am using the tlc272 to make an instrumentation amplifier, the resistors i used are all same value which is 91k, when i measure the Vout and ground. I get impedance around 645k ohm. does this normal?

  • RE: INA331 Output noise when using amplification configuration via external resistors

    Resolved
    Hello Christian, First, have you looked at the input pins, supply voltage, and reference voltage pins on an o-scope? If so, can you please post the waveforms? From here I recommend isolating and testing the INA331 by doing the following: 1) Remove R1,…

  • gain and offset

    Resolved
    Other Parts Discussed in Thread: TLC272 , TINA-TI i am using the tlc272, i was trying to gain it using the 1st amplifier, then offset it using the 2nd amplifier. the 1st amplifier work good. for the 2nd amplifier (use for offset), i use voltage divider…

  • RE: LF353 offset level changes from part to part

    Resolved
    Hello Pedro, Those were the lowest cost devices for DIP R-R input devices. R-R devices are going to cost a little more. The LF353 is a 30 year old device. DIP packages are going the way of the dinosaur - so requiring DIP package is limiting your choices…
