• RE: Is it possible to compensate the gain drift of the AD8421 with a resistor of known drift in ppm/°C ?

    Thank you Emman for this competent reply.

    Up to recently we have been using the AD621 which has internal resistors, a low gain drift of 5ppm/°C and a noise of 9nV/√Hz.

    The AD8421 was attractive because of its much lower noise of 3.2nV/√Hz, suited for…

  • INAMP_CMRR in single power supply and dual power supplies

    I wanted to know whether the CMRR will be influenced by this different
    conditions?
    Take AD8221 for example.
    Case 1: supply the +5V single supply to it, the input signal will be Voff=2.5V,
    and the AC signal (under the frequency of 10Hz) to AD8221…

  • RE: Load Cell Amplifier

    Hi IsmailCetinkaya,

    I can speak to your instrumentation amplifier requirement. To get this kind of gain drift in an instrumentation amplifier, you will need to use an in amp with integrated gain resistors. A zero-drift amplifier solution will offer no…

  • RE: Dual AD620 sharing same resistor.

    Hello josiah47,

    Two AD620s will not work with the same Rg network. The reason is that the in-amp works by forcing the differential voltage between the inputs to appear across the Rg pins. If you short the Rg pins of the two AD620s together, they will…

  • Load cell signal chain

    Hello,

    I design a signal chain for a weight system.

    I have up to 8 load cells on my system (0.55 mV/V at 5000Kg)

    I want to be able to read each cell independently.

    I have some questions concerning that:

    1 - Sensor supply:

    I know lower is the suppllower…
