• LT1461 in Parallel

    Hi,

    Can i put the LT1461 in parallel in order to get more output current?

  • LT1461 output ringing

    Hi, I'm using the LT1461 4.096V version as an ADC reference for the AD7989-5. I have the output decoupled with a 10uF X5R 50V ceramic capacitor. Input power is +5V.

    For my noise test my DC input voltages are

       VIN- = 3.96V

       VIN+ = 0.13V

    I perform…

  • LT1461 shutdown pin open

    In my circuit, shutdown pin is left open and the output voltage has changed from 2.990V to 3.000V in a hour

    When I shutdown pin leave open, is output voltage affected?

    Or do I have any other potential problem in my circuit when the output voltage change…

  • LT1461 DNC pin problem

    Hi ADI team,

    There are four DNC pin for LT1461, and I found that the DC impedance is only 5ohm between pin7 and pin8. Another samples show around 0.83Kohm between pin7 and pin8, and the voltage works well for 3V output.

    I put my all measurement below…

  • LT1461 SHUTDOWN pin max voltage = ?

    I would like to know what is the maximum allowed voltage on the SHUTDOWN (/SHDN) pin of the LT1461 voltage reference.  The datasheet is not clear about this.
    For example: can /SHDN be connected to VIN, when VIN = 15 Volts ?

  • What is the output impedance of LT1461?

    What is the output impedance of LT1461?

    Hello,

    I am using the chip of LT1461 to make a 5V reference voltage, and behind the LT1461 is a amp circuit.

    Now, I want to know the output impedance of LT1461 to fiure out if the behind circuit will affect the…

  • What is the output impedance of LT1461 ?

    Hello,

    I am using the chip of LT1461 to make a 5V reference voltage, and behind the LT1461 is a amp circuit.

    Now, I want to know the output impedance of LT1461 to fiure out if the behind circuit will affect the 5V output of LT1461.

    But the datasheet doesn…

  • Can the LT1461 be stacked in series to achieve nonstandard reference voltages? Is there a current sourcing capability penalty for doing so?

    I'd like to place a 5v and a 4.096v LT1461 in series driven from the same 12v rail to get a 9.096v output at 50mA. Is this possible or will I have issues floating one above ground in this fashion?

  • RE: LTC2312 Internal Reference - Long-Term Stability

    Hi,

    There is no long term stability data available for the LTC2312 internal reference. If this is important to you I would recommend using a different ADC that supports using an external reference with specified long term stability. An example would be…
