• LT1994 Temperature overheating

    Hello engineers

    Why the designed analog signal sampling circuit will cause the LT1994 to overheat,Can you give me some help?  

  • LT1994 Bandwidth

    Hi

    My customers are considering LT1994 and received questions about bandwidth.

    <conditions>
    Input signal: ± 1 V
    Gain: × 4

    #1   What is the bandwidth at this time?
           Considering from GBP (70 MHz) when Vs = 3 V,
           Is it about 70 ÷ 4 = 17.5 MHz?

    Best…

  • RE: AN-159 LNA BOARD NOT WORKING

    Hi Erkan,

    Apologies for the late reply. 

    I took a look at your snapshots and saw some LT1994 units had wrong orientation. This is likely the cause of the board not working as expected.

    In parallel, we'll work on fixing the mask issues on the board to properly…

  • RE: I am designing a circuit for driving a differential input ADC. As operational amplifier I use LTC 6254. My design works fine when simulating in LT Spice. However, when it comes to analyzing one of my outputs using a spectrum analyzer voltage level...

    Yes my input signal is always below 5MHz.
    I have looked through the differential amplifiers you suggested  AD8139,    LTC6404-1,  ADA4940,  LT1994.
     
    One other requirement in my design is that the input source is a high impedance…
  • Amplifiers power consumption ambiguity

    In LT1994 by 150 diff load and 3.3 single supply yo can see this:

    At the right side of picture you see "power". It says 23.1mA into Vcc! and 18.8mA from Vee!

    First OpAmp must sink current from Vcc not sourcing to it!!!! secound why these (from…
