  • OPA378: Can you really use a chopper in a high gain Transimpedance design?

    Resolved
    Part Number: OPA378 Other Parts Discussed in Thread: OPA392 , OPA387 , OPA333 So this is following up a bit on this earlier OSI photovoltaic design question. I got to thinking about how to really do this when offset voltage is critical - https://e2e.ti…

  • OPA392: EMI hardening vs filtering

    Resolved
    Part Number: OPA392 Other Parts Discussed in Thread: OPA378 Tool/software: Hi TI, What is the difference between EMI hardening and EMI filtering? Some opamps (e.g. OPA378) are labeled as 'EMI hardened' while some (e.g. OPA392) are just(?) 'EMI filtered…

  • OPA378: circuits and amplifier as a reference buffer

    Resolved
    Part Number: OPA378 Other Parts Discussed in Thread: REF3125 , OPA625 Hi team, My customer want to use the reference REF3125 to drive 0-5mA (PWM, 4.8khz), Do we have some recommend circuits and amplifier to support the requirement? if we have the simulation results…

  • RE: ADS1299EEGFE-PDK: What is the amplifier "U2" in ADS1299EEG-FE Performance Demonstration Kit?

    Hi Saurabh - my mistake. It looks like the U2 footprint is for an SC70 5-pin package. Perhaps consider the OPA378. Regards, Ryan

  • RE: 2nd order butterworth MFB active filter design

    And to move my design down to a slower, lower Icc, but slightly higher input voltage noise design, the OPA378 looks promising, And this file, 20kHz MFB LP improved RC values OPA378.TSC

  • OPA378 1/f or Flicker Noise

    Other Parts Discussed in Thread: OPA378 , OPA348 Hello, The OPA378 op amp shows 0 (zero) 1/f or Flicker noise. Could you please explain why that is? Thank you, Keith

  • RE: OPA348: What's wrong in this double stage SK LPF?

    Ok, I spent some more time on this so might as well share some results - 1st I tried to find a closely related part that might run successfully in my V11 TINA version, the OPA378 is a similar speed but chopper - it also crashed on noise (TINA shut down…
