• AD822: PSRR

    I would like to get support regarding the power supply rejection value of the
    component AD822. The data given in the tables are referred to the input or the
    output of the opamp?

  • AD822:Asymmetrical supplies

    In my application the AD822 gets dual supply, but not symmetrical:
    V+ = + 24V and V-= -5V. The AD822 drives a load of 4 kOhm against analogue
    ground.
    Does work the AD822 with the unsymmetrical supply voltage in a proper way ?

  • AD822 max. Output Current

    Hi,

    I'm referring to the official datasheet of the AD822 operational amplifier.

    https://www.analog.com/media/en/technical-documentation/data-sheets/AD822.pdf

    It states a minimum value of 15 mA of output current, but no typical or maximum value is…

  • History of AD822 data sheet

    Hello

    I am tracking the history of the external dimensions of the AD822 at the request of the customer now.

    I read that the AD822 (SOIC) has changed the external dimensions five times in the past and also converted to halogen free.

    I'd like to check…

  • Is it safe to test parts attached to unpowered IC's?

    Flying-probe testing of components attached to inputs and outputs of an AD822 is desired in unpowered avionics boards. Testing diode forward voltages at 1mA and 10mA is suggested, possibly supplying these currents at voltages up to 1.3V between any input…

  • ad822: Phase reversal (1)

    A customer is reporting a behavior of the AD822 as follows:
    If an input gets a voltage level that is above the Vdd, the output is going low
    instead of staying at Vdd potential.

    ° Would it be possible to get some infos on the background…
  • AD822: Input Overvoltage protection

    Is it allowed to have +-30V at the input, if the part is not powered.

     

    The AD822 cannot have +30V or -30V applied to either input when there is no
    power on the supply pins. As a general rule, the absolute maximum current into
    a pin should…
  • AD822: Phase reversal

    Tha datasheet states that the opamp AD822 do not phase invert the output signal
    when the input signal exceeds the supply voltage, but it does. How can that be?

     

    It is important to distinguish between over-voltage protection (i.e. the
  • AD822: Overvoltage issue

    The problem I have is as follows: I am having to apply a signal of
    approximately +/-1 volt to the -ve input of one amplifier in an AD822, while
    the device is unpowered. This event occurs only once, during our system
    proving, and the signal…
