• LT6018 simulation

    Why is this LT6018 circuit showing 5uA input bias whereas the spec calls 40nA typ 150nA max?

  • Can we limit the current output of current booster circuit using a single resistor?

    Hi, we are building hight current boosters using the reference design of AN18 Figure 2. LT1010 Based Output Stage.

    Figure 2 of AN18

    In this design we are replacing LT1056 with LT6018 using exactly the same topology (is it OK?) and the current are boost to 8A by replacing…

  • How to simulate the current boost amplifier using ltspice? (Designed by jim williams, AN18)

    Hi, I am planning to build a current booster using LT6018 + LT1010, using the circuit of Figure 2 from AN18 written by jim williams.

    Though in this post, About the current boost amplifier using LT1010 (AN18) - Q&A - Amplifiers - EngineerZone (analog.com…

  • About the current boost amplifier using LT1010 (AN18)

    Hi, I am designing a high current driver after a precision DAC (AD5781). I found the circuit from AN18: Power Gain Stages for Monolithic Amplifiers. In Figure 02, It uses a current boost design of NPN + PNP after a high current buffer LT1010, which is…

  • Composite amplifier using ADA4637-1 and ADA4870-1

    I want to build a composite amplifier using the Figure 77 of the datasheet ADA4870-1. It says that the voltage offset is less than 500 uV. I simulate this circuit using LTSpice, when driving ada4637-1 with 0V and monitor the output of ADA4870-1, it is…

  • RE: 请教选择一款低噪放芯片

    LT1028,LT6018是ADI的最低噪声运放。建议搭建带同滤波器,并用LTSPICE进行仿真。

  • RE: Choices of amplifiers for AD5781/91

    Since you are constantly varying the DAC code, yes you should opt to use the AD8676 for the reference buffer.

    You should also use the LT6018 as the output buffer if you need the fast settling time.

  • RE: LT1028 Current Noise - Differential - Common Mode

    Hi Gerd:

    With balanced source impedance, the differential (incoherent) current noise is measured, as the common mode (coherent) is cancelled.   At 14kHz I found 1pA/rtHz incoherent noise (balanced source) doing the Erdi calculation of dividing by 2Rs.  Common…

  • RE: ADA4870 as a high current driver after a high precision DAC (18, 20 bits)

    Thank you. I notice that figure in the Datasheet and would like to use a combination of AD8675 (or LT6018) + ADA4870 to build this composite amplifier. I also want to maintain the precision of ADA4870 for high current drivers. How could I build a power…
