• REF01: Long term drift

    I have selected the REF01AJ or
    REF01AZ which should be ok for my application. However, I cannot find the
    information regarding long term stability. Please could you forward it to me
    for standard and /883C versions ?

  • RE: REF01 Internal trim adjustment circuit

    Hi Jiro,

    As stated in REF01 data-sheet "Newer designs should use ADR01". ADR01 offer high accuracy and temperature stability over wider operating range and maintains full pin to pin compatibility with the REF01. After analyzing the schematic R5 = 35k…

  • Noise problem with a REF01 with booster transistor

    Hello all,

    I have a noise problem at an oscillator starting at abt 100 kHz up to abt 1 MHz offset from the carrier (see picture).

    I measured the spectrum of the power supply - and there is a remarkable noise increase around 500 kHz +/-.Problem located…

  • LTC 4421 and LTC 4418

    we work on a robotics system with  Three 48v Battery pack. I want to design a board in order to switch between three batteries based on the priority.

    we need a circuit with a max 40A pike. I found LTC4421 and LTC4418 for this work. As I read in the datasheet…

  • LTC 3813 2KW


    I use LTC3813 to do 2kw boost converter ,but i saw low side mosfet PWM as below picture,its frequency change,this behavior is normal or abnormal?

    bulk voltage=75v ,and connect to 12V DC/DC load 20A

    CH1: Low side MOSFET PWM

    CH2: BULK voltage

  • DEMO 2459A, LTC 1668 interfacing with zedboard


    I am interfacing the Evaluation board Demo 2459A-C with IC LTC 1668, with FPGA. I am generating the frequency 455KHz but it generates harmonics along with this frequency. 
    Is there any interfacing issue or I have to kill the harmonics myself after…

  • LTC 2291 Timing Diagram for multiplexed digital output

    Hello all,

    I have got a question to the timing diagram for the multiplex digital output bus timing for the LTC2291 on page 14.

    There are two delay's for the multiplexed timing diagram: tD = CLK to DATA Delay and tMD =mux to data delay.

    Now my question…
