• RE: Question on Lt1013D

    Hi Vipul:  That circuit uses the resistors to divide the input common mode by 2.  So it brings your 35V down to 17.5V, which is still outside the 13V or so common mode capability of the LT1013 on 15V supply.   You need to ether increase the 2 series input…

  • Circuit Oscillation Analysis

    I have the attached circuit as a Voltage Controlled (V_Control) Current Source (I-Load).

    This circuit has an stability issue. When V_Control drops from 3.3 V to 0 volts the circuit works fine at room temperature. But when the temperature is reduced to…

  • RE: Used one OpAmp as Amplifier and another as Comparator in a ADA4891-2ARMZ chip. Can the usage of a OpAmp as a Comparator for this device cause any trouble, wear-out etc.

    Comparators, Op Amps, and InAmps are shown as triangles with two inputs and one output;  they are not the same.

    A comparator is decompensated, has a digital output stage, gets faster w/ overdrive, and usually will allow a wide

    differential voltage on…

  • RE: OP284 oscillationg

    Thanks for looking at this. That's good information. 

    Just out of curiosity, I simulated the OP284 with the LTSPICE "Test Fixture" .  The test fixture runs at a gain of 2.  That ran fine.  However, when I took that Test Fixture and changed…
