  • THS4500: Source impedance affecting amplifier gain

    Resolved
    Part Number: THS4500 Hi, The THS4500 datasheet's fully differential amplifier configuration assumes a 50 Ohm source impedance. However, in the presence of the 50ohm source impedance, the gain is affected by a factor of 1/2. In this circuit, I expect an…

  • THS4500: Is a termination resistor Rt necessary for V+ if a buffer stage is used?

    TI Thinks Resolved
    Part Number: THS4500 Other Parts Discussed in Thread: THS4561 , LMV796 I plan on using a buffer at V+ of THS4500 as shown below. Is a termination resistor before R3 necessary as specified in the datasheet? If so, how is the value determined in the absence…

  • RE: TLV9041: TLV9044

    Hello Jinisha, THS4500 is available in commercial form.

  • RE: THS4551: Alternative part

    is ths4500 or 4501 are suitable ? because we need higher slew rate and bandwidth like ths4511 but it should work in higher supply voltage , please let me know your comments

  • RE: LMH6551: Frequency response : gain = 2~10

    Resolved
    Since the LMH6551 model seems suspect, there are other TI +/-5V capable FDA's to consider - the THS4500 to THS4505 might fit your needs as well.
