• ADP1761 variable output voltage

    I would like to use the ADP1761 in a low noise application, where the output voltage can range from 0.6 to 1.0 volts (900mA maximum).

    The control of this should be via some bus such as I2C / SPI.

    Are you able to recommend a suitable controlled resistor…

  • RE: Vdropout data of ADP1740/41

    Hi Hiroyuki,

    I recommend you use ADP1761. It is a low VIN, low noise LDO with VIN range from1.1V to 1.98V  and an adjustable VOUT range from 0.5V to 1.5V which covers the customer requirements. Also its dropout for VOUT=1.2V at 1A is at ~53mV maximum.

    Best…

  • RE: Noise below 100Hz in ADP1762/ADP1764

    Hi Atownley,

    Yes there's a difference between the ADP1761/2/3 and ADP1764/5 in terms of noise performance. The noise filter in ADP1764/5 was improved and cutoff frequency is lower compared to that of the ADP1761/2/3 so more flicker noise are filtered…

  • RE: Power good resistor; default SS time; figure error

    Hi Ben,

    1. The PG pin is an open drain connection. If not used, leaving it open is just ok but tying it to GND is better.

    2. Figure 25 of ADP1761, ADP1763 is correct. Please refer to that. Equations 1 and 2 are applicable above a certain Css (Css > 10nF…

  • ADP1763 Output capacitor

    Hello,

    I would like to use the ADP1763 for a design and I need some clarification regarding the choice of the output capacitor.

    The datasheet recommands to use a 10 µF capacitance with an ESR of 500 mOhms or less to ensure the stability.

    The output…

  • output voltage tolerance calculation ADP1762-ADJ

    Hello,

    I would like use ADP1762 adjustable LDO.

    My application needs power supply +0.975V +-0.025V (≙ accuracy 2.56%) at 1.7A.
    Supply voltage tolerance sourced to LDO input is +1.8V +-0.1V.
    Ambient temperature definition from 0°C to +40°C.

    How I have…

  • RE: AD9163- recommended LDO for 1.3V

    ADP1761 is a good choice as LDO for the overclocking purpose.

    "1. what is the load change that the LDO will see from the DAC ? I need it to select the required "load regulation" spec for my LDO. "

    -- VDD12_CLK is the most supply…

  • RE: 我最动芯的ADI新品评选

    ADI的新产品中用的最多就是 ADP1761和ADP7152。感觉主要优点就是器件尺寸小,电路设计简单,大电流输出的同时电源噪声保持非常低的水平。在我们设计的射频系统中起到了关键的作用。保证了我们的通信系统信号质量达到了非常优的状态。

    另外最近在研究AD9371,超宽带软件无线电,这款芯片有望颠覆现有的很多通信系统。
