• ADA4897-1, ADA4897-2, ADA4896-2 Maximum Operating Voltage Range

    Will the ADA4897-1 run off a single +5V or +12V Supply Range ?

     

    On pages 4-5 of the data sheet you will find the operating parameters for +5V
    supply range. According to the data sheets, the ADA4897 has a normal operating
    voltage range…
  • ADA4896-2\ADA4897-1\ADA4897-2

    请问这三款除了引脚不一样,集成运放数量不一样,4897带了使能端之外,4896与4897的性能是否一致?

  • Input Bias Current Drift / ADA4896-2

    Please teach me ADA4896-2.

    Do you have Fig for  'Input Bias Current Drift Distribution' vs 'NUMBER OF PARTS'

    My requset is similar of Fig24.

    Please change 'Input Bias Current Drift'.

    Thank you.

  • ADA4896-2 output saturating in unity gain

    Hi

    I have a design that uses a ADA4896-2 in unity gain mode. I have a 5V and -2V supply. The amplifier drives a analog switch, ADG719. The amp works fine if I have the input voltage below about 4.3V. If I then increase it the output just saturates at…

  • Audio Amp questions about AD8397 and ADA4896-2

    Hi Sir,

        Our customer have interesting in AD8397 and ADA4896-2 , and have questions need to know further about :


    " How do these parts(AD8397 and ADA4896-2) behave when they reach their output current limits?

    Do they clip at Io limit, is the…

  • Opamp ADA4896-2 quiescent current difference datasheet vs measure

    Hi, I have designed an Analog Front End with two opamp stage ADA4896-2.

    The power managenment is very important for the project, I need to dimmensionned the voltage regulator for the good current to limit the components area.

    The voltage supply is 5.3V…

  • ADA4896 noise simulation

    Hi,

    Regarding ADA4896, I tried to simulate for noise performance by using MultiSim, but it was not the level that I expected.

    The noise level result is 1.0188e-16[V^2/Hz]. I think that the correct value is 8.84e-18[V^2/Hz].

    And there is no 1/f noise…

  • ADA4896 simulation model

    Hello all, 

    In the course of consulting on a channel requiring a low noise non-inverting gain - there was also a need to inject a DC offseting level through the inverting Rg path - this needed to be broadband low noise where the ADA4896 seems ideal for…

  • ADA4896 oscillates at ~90MHz

    We use ADA4896 as unity gain buffer, single power supply (0V, +5V). Schematics is attached to the message. We connect input to the laboratory voltage source. We observe oscillations at ~90MHz. The amplitude of the oscillations varies between 0.3V and…

  • ADA4896 LTspice model noise vs temperature

    When simulating voltage noise versus temperature of an ADA4896 in follower configuration:

    I observe a huge increase in voltage noise spectral density ranging from 0.95 nV/rtHz at 25 °C to 8.9 nV/rtHz at 105 °C (at 10 kHz).

    This seems unrealistic…
