  • RE: High speed amp for 20Vpp signal

    Hello Jonah, I will ask around, but I have not yet found any data on my end characterizing the parts mentioned (THS3120 & THS3121). If you have any other questions for me to look into, please continue asking away . Best, Alec

  • THS3120: THS3120ID & LM6181IMX-8

    Part Number: THS3120 Other Parts Discussed in Thread: TINA-TI Hi, Need your advice to understand why I could not use the THS3120ID as Alternative to LM6181IMX-8 – It doesn’t work on my circuit Please see below Schematic + Compare of the c…

  • THS3120: PowerFET drive circuit didn't work

    Resolved
    Part Number: THS3120 Hi Dears, The datasheet of THS3120 shows a PowerFET drive circuit, but it seems that this circuit is not correct. The output voltage of THS3120 is from Vs to -Vs, while the source voltage of P channel MOSFET is -Vs, the Vgs voltage…

  • THS3120: Excessive heating

    Resolved
    Part Number: THS3120 Hi, I recently built an analog buffer board using this IC. Please find attached the schematics. After I power up, I am observing that the op-amps are getting excessively heated up. I am observing this heating even when there is no…

  • THS3120: Looking for recommendation for high-speed, high-current output capability amplifier

    Resolved
    Part Number: THS3120 Other Parts Discussed in Thread: , THS6012 , OPA2673 Hi, Is there a newer, higher-current amp you would recommend over THS3120? I am planning on designing a setup to test PSRR as described in the SLAA414 application note. The application…

  • RE: TPS74801: TPS74801: questions for PSRR test

    extra two questions need you help to check: 1. customer to add 1V peak to peak AC signal to the input, but only 8.8mV measured show in the scope, do you know why? I saw the document use THS3120 for measurement, does it means we need to tool for PSRR testing…

  • THS3120 High Current Pulse Tolerance

    Other Parts Discussed in Thread: THS3120 , OPA2673 I’m trying to use the THS3120 for a design but am concerned about high current pulses in my system on the output pin. The datasheet only specifies the continuous output current capability, which is…

  • RE: OPamp recommendation

    Resolved
    Gentlemen, thanks for your input. I have recommended to use either THS3091 or THS3120. Of course the customer will have to take care of a proper layout to achieve the desired input capacitance! Best regards Carsten
