OPA2670: Simulation Model for Part No:-OPA2670

Part Number: OPA2670
Other Parts Discussed in Thread: TINA-TI, OPA2675, OPA695

Hi,

I have used OPA2670 for our new design. So please Could you give me TINA-TI model of OPA2670 asap?

Best regards,

Niranjan

  • Hi Niranjan,

    Can you check OPA2675 specification also once, it's a newer device and if it meets your requirement, I would suggest to use this instead of OP2670.

    TINA model for OPA2675 is also available in TI.com.

    Regards

  • Hi Anant,

    I have to check the OPA2675 specification, it's a dual Input and output amplifier and we have required a single  I/P and O/P channel.

    So Can you suggest any other amplifier instead of OP2670,Which has less flatness in the entire 50 MHz BW. and capable of 10 Vpp Output.

    Regards

  • Hi Niranjan, 

    Both OPA2670 and OPA2675 are dual channel current feedback amplifier targetting similar application having same package and pinout.

    For your application do you need a current feedback amplifier or a voltage feedback amplifier. What's the slew rate you need?

    Regards

  • Hi Anant,

    We want to used Current feedback amplifier and slew rate should be high i.e grater than 2500 V /usec. So please suggest accordingly.

    Regards

  • Hi Niranjan,

    Please check OPA695, it's 12V current-feedback opamp having slew rate of 4300V/us.

  • Hi Anant,

    Greeting of the day
    Thank you for your support for Amplifier part No :)
    Now We are required to use a 50 MHz BW Differential Filter for our new design and development. So kindly suggest a part number which has insertion loss <1 dB and gain is 0 dB within 50 MHz BW, and has differential input and differential output. Can u suggest TI part no of differential filter?
    Regards,
    Niranjan
  • Niranjan,

    I am closing this thread here, for differential filter design, we will look for the part to fit your requirement and communicate it to you in the other thread you created.

    Regards
