• Simulating LT1166-based Current Source in LTSpice

    The following circuit operates on the bench but isn't stable with a zero load (as shown: R8 is the output current sense resistor):

    (Most components are as shown, but the FETs and the 2.5V references are different in the physical circuit, and the…

  • RE: About LT1166

    With those small 100V transistors, I would not expect over 100W into 8 ohms (about +/-40V swing) and a couple slices to ease the heating. For 350W into 8 ohms, the swing is almost double that, so devices of at least 200V would be needed and 9A peaks, so…

  • RE: LT1166控制的功率级偏压,在工作时比如上管5A电流,下管是否会截至或者下管还是在LT1166设定的静态电流下。

    The output devices will both be at quiescent setting when not delivering current to the load, but as one device delivers load current, the other device will be controlled to a lower current than quiescent, but not to zero current. If quiescent was set…

  • LT1166 questions about reference design on datasheet

    Hi all,

    I have 2 questions for LT1166 when I reading the datasheet. hope someone really familiar with this IC can help me on this. really thanks a lot.

    Q1:

    what are the major differences between using LT1166 as current source drive and bipolar buffer…

  • RE: LT1166 当正偏压时。上管工作,下管的电流是否还是静态时候的电流

    The purpose of the LT1166 is specifically to prevent the non-linear cutoff of the classic class-B circuit by maintaining a continuous though reduced bias on the device not providing the load current. Look at the LTC6090 datasheet for an example.

  • LTspice ADHV4702-1

    你好,

    我需要輸出+-60V/1Aout的1KHz Sine wave,所以選了ADHV4702-1加上LT1166來模擬,發現在一開始的時候,輸出端有個pulse出現,

    於是參考ADHV4702-1 datasheet內的TYPICAL APPLICATION CIRCUIT 模擬,但是輸出總是會有一個pulse出現.

    於是改成Unity-Gain Buffer,並且輸入端下地,依然輸出有一個pulse出現.

    請問該如何解掉這根pulse呢?謝謝.
