• Does AD680 have high impedance mode?

    We designed to connect AD680 to four AD7741 at 2.5V.

    When the pull down resistor was 20kΩ, the voltage of AD680 drops from 2.5V to 2.35V. And when the pull down resistor was changed to 500Ω, the voltage drop was eliminated.

    Why is the problem…

  • RE: AD680 adding tow capacitor

    Hi, Osamu.

    According to the applications engineer of AD680, ADI does not guarantee the performance of AD680 when a capacitor is connected between the TEMP pin and ground because AD680 was not designed for that purpose.

    As alternative, you may try the…
