• ADR4525, ADR130

    Hi ,

    I am using ADR4525 as a 2.5 V reference and ADR130 as 1V reference .I understand the maximum junction temperatures of these parts cannot exceed 150C but I intend to test at 175C for few days 

    The input voltage for ADR130 is 2.5V from ADR4525. When…

  • Do I need to put a buffer on the ADR4525 output?


    I will use ADR4525 as a reference source to an ADC, and would like to know whether I need to put an output buffer or not. What should I consider?

    Thanks in advance.

  • Differential Amplifier for 32-bit ADC

    I am working on an VirtualBench Projects that uses the AD7177-2 32-bit ADC.

    Does anyone know any good amplifiers that wil work well With the 32-bit ADC?

    I am looking at these parts.

    External gain: AD8253

    5.00v ref: ADR4550

    2.50v ref: ADR4525


  • RE: ADR421- Can the IC clamp current or sink current at its output.

    Hi kiranlal,

    The ADR421 is not designed/specs to sink current. But we also have ADR4525 which can sink and source current up to 10mA.



  • RE: EVAL-AD5766 Issues


    Kindly let us know if the new chips resolves the issue.

    Can you also quickly check if the reference (ADR4525) has a correct output of 2.5V +/-1%?

    Best regards,


  • RE: Transient behavior on first samples of AD7980

    Hi Percy,

    From the AD7980 data sheet:

    When REF is driven by a very low impedance source, for example, a reference buffer using the AD8031 or the ADA4805-1, a ceramic chip capacitor is appropriate for optimum performance. If an unbuffered reference…

  • RE: AD4110-1 RTD function (excitation current)


    The typical configuration when using the RTD functionality is to supply the REFIN(+) and REFIN(−) pins of the AD4110-1 from an external precision 2.5 V reference, such as the ADR4525.



  • RE: ada4927-1 adding dc offset onto inverting input to maximize adc range



    Are you talking about the inverting input of fig 48 of the rev A data sheet?

    If so, the circuit simply sees two signals and takes the difference.  It doesn't

    know that one is a DC offset.

    However, I would NOT use an LDO for the offset.
