• ADA4870

    hi
    I want to ask if I can work with ADA4870 with single supply voltage. but I want to work only with 5V and connect VEE to GND.
    Is it possible?

    Thank you

  • ADA4870

    Hi supporter,

    I'm currently designing a non-inverting amplifier using ADA4870.

     

    However, I accidentally leave SHUTDOWN pin (pin 3) floating.

     

    My questions are:

    i) What will the amplifier output behave when SHUTDOWN pin is floating? Will the…

  • RE: ADA4870 as a high current driver after a high precision DAC (18, 20 bits)

    Thank you. I notice that figure in the Datasheet and would like to use a combination of AD8675 (or LT6018) + ADA4870 to build this composite amplifier. I also want to maintain the precision of ADA4870 for high current drivers. How could I build a power…

  • ADA4870 Short Circuit protection using issue

    Hi Experts,

     

    I saw below in Page19 of ADA4870 spec.

     

    ON, INITIAL POWER-UP, AND SHORT-CIRCUIT After initial power-up, the ON pin must be pulled low to ensure that the amplifier is turned on. Subsequently, floating the ON pin enables the short-circuit…

  • Can ADA4870 output voltage beyond 40V?

    Hi, everyone! I am trying to drive a ultrasound sensor with ADA4870, but the supply voltage can not exceed +-20V. Is there any way to use one more ADA4870 ICs to generate a voltage beyond 40V, like 60V?

    您好,

    我这边仿真是没有问题的。建议把ADA4870的spice model 重新建一遍。

  • ADA4870 for high output current voltage buffer design

    Hi all,

    I am willing to use ADA4870 for the design of a voltage buffer (low output impedance) with >1A output current. Anyone suggesting a reference design with the use of more than one ADA4870  chips?

    Thanks.
