  • THS4271: require theta Jb value

    Part Number: THS4271 Hello, Could you please tell me the thetaJb of THS4271? One customer need this value. Best regards Kailyn

  • THS4271: Distribution amplifier 10MHz with Dliyannis structure filter

    Part Number: THS4271 Other Parts Discussed in Thread: LMH6723 , , LMH6609 Dear Sir, I design a 10 MHz distribution amplifier with a band-pass filter at the input. I used the THS4271 amplifier to build the filter, and the LMH6723 amplifiers for the output…

  • TINA/Spice/THS4271: Single-supply vs Dual supply AC Simulation Differences??

    TI Thinks Resolved
    Part Number: THS4271 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models I am getting differences in the simulation when using single-supply vs dual supply. I tested with the THS4271, and OPAx828 TINA-TI Spice Models. The OPAx828…

  • THS4271: Driving a high frequency ac ripple through an LC bias tee

    Resolved
    Part Number: THS4271 Hi, I was considering a design as shown below where the THS4271 amp drives the AC input (80MHz, 50mVpp sine wave) to an LC bias tee composed of a 2.2uH inductor and 100nF capacitor. DC is assumed to be driven by an ideal DC power…

  • THS4271 input protection

    Other Parts Discussed in Thread: THS4271EVM-UG , THS4271 I appear to have blown up the THS4271 on the THS4271EVM-UG. It worked very nicely out of the box. Then we removed the 50 ohm input resistor since I'm using it as a high impedance follower When…

  • RE: Oscillation issue on THS4271

    Resolved
    Hi, I also am seeing oscillation with a THS4271-based circuit and am wondering how you resolved, or if you did, this issue from back in 2011. Ken Aquino

  • THS4271 transimpedance amplifier with -50 mV bias - power sequencing issue

    TI Thinks Resolved
    Other Parts Discussed in Thread: THS4271 , THS4031 , LMH6629 , OPA820 , LM13700 Hi Samir, I did fix the problem by modifying the voltage regulators so that the + supply comes up first and then enables the - supply. However, I want to understand the problem…

  • THD of THS4271 is bad in inverting configuration with gain=1

    Resolved
    Other Parts Discussed in Thread: THS4271 , THS4271EVM-UG Hi, I am evaluating the THD performance of THS4271. In the non-inverting configuration with gain=1, THD comes to around 82dB, but in the inverting configuration with gain=1, THD is about -71dB with…
