• LT6018 simulation

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

  • 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: 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…

  • how does filter wizard calculate low-pass filter noise?

    Would like to know how the filter wizard does this calculation. It's obvious that the opamp's en and johnson resistor noise are components but would like to see how they combine. How does each stage contribute? Can I reverse stages? Seems like, for example…
