• AD8628 minimum stable gain

    The datasheet does not mention the value of the minimum gain. What minimum gain
    is possible, where AD8628 stays stable?


    AD8628 is unity gain stable. This means G = 1 or G = 0dB.

    Most of our amplifiers are unity gain stable, unless…
  • AD8628 Spike bias current

    Auto zero amplifiers,like opa2188 ,have spike bias current which is very huge.The datasheet of AD8628  did not mention spike bias current,does AD8628 have very low spike bias current or it does not have any spike bias current?

    What series resistor value did you add? Can you attach your circuit for better understanding including the voltage input and power supplies values? Thanks.

  • AD8628: Signal sourcing

    Reading the 8628 data sheet I don't see the simplified block diagram of the
    amplifier. The question is the following: when looking to the signal source
    trough AD8628 is that mean that 8628 connected to the signal source only half
  • RE: AD8226 Application Suitability - MEMS Accelerometer

    Hi Harry,

    Thank your for your reply. The AD8628 was in fact my second option for the filter. I only went to the ADA4528-1 because it was cheaper than the AD8628 in 3 of 4 distributors. Also, although on paper every calculation seemed ok, I got weir results…

  • 你好,有个AD8628的问题想问一下



  • AD8628/29/30, thermopile application, power supply decoupling?

    We are attempting to use an AD8630 to amplify the signals from four thermopiles.  This amplifier was recommended by Dexter Research, a thermopile manufacturer.  One thermopile is equipped with broad-band optical window which admits a lot of light, and the…

  • RE: AD5064 driving capacitive load


    Yes the DAC could become unstable as we have not characterised the amplifier beyond this. The lowest resistive load is 5K.

    You could investigate the use of the AD5066(Unbuffered version of the AD5064) and an external low-noise low-offset op-amp…

  • AD8628 vs ADA4528-1 Output Current Capability


    Looking at Figure 11 (Ouput Voltage to Supply Rail vs. Load Current) of the AD8628 datasheet it can be seen that you can get up to 10 mA at the expense of about 400mV drop from the supply rail.

    From Figure 15 of ADA4528-1 it seems that you can get…
