  • LTC6244 Alternatives for peak detector

    ShlomiP323
    ShlomiP323

    Hi All,

    I started to work on a peak detector using LTC6244 and according to ADI app note (https://www.analog.com/en/technical-articles/ltc6244-high-speed-peak-detector.html). 

    However, I don't have LTC6244 in my lab so I used another OpAmp - ADA4077 and…

    Hi,

    I'm trying to simulate the following circuit and can't get it to work in LTSpice without 1.2 MHz oscillations.
    What could I do to make the simulation work as expected?

    The circuit is from page 19 of the LTC6244 datasheet.

    Thanks

    Here's my LTspice…

    Hi shurp,

    Kindly refer to this article:

    LTC6244 High Speed Peak Detector

    Let me know if this helps.

    Hi 

    I dont have LTC6244 part right now.. So equivalent OPA656 was used which is available with us.. 

    AD8038 IC is available, can I use that instead of LTC6244??

    Hello,

    From the article, the LTC6244 was selected due to its AC performance, wide supply range, offset voltage, and drift.
    The LTC6244 has much better Vos and and drift as compared to AD8009.

    One important note here is that, AD8009 is a Current Feedback…

    you might also want to look at the LTC6244 datasheet for some really neat TIA circuits based on JFETs and op amps. This might improve your system level design. We have JFET models in LTspice - or you can import a third party model

    Hi jgirgis:  The low frequency performance is dictated by the hold capacitor and the bleeder resistor, C2 and R14.  (Or, in the linked LTC6244 circuit, C1 and R4.)

    Hi Rahul,

    Regarding the LTC6244 Figure 9a schematic (Fully differential buffer / amplifier) operation:

    I don't have any app note that describes how the circuit operates. However, I've looked at it a little and I can offer this explanation as to the circuit…

    Hi Robert,

    For the peak detector circuit, we have the ADA4622 which is optimized for this type of applications. You can take advantage of the dc precision and super low bias current to get a highly accurate circuit. It also has a sample circuit discussion…
