• AD8541 AD8542 AD8544 noise (low frequency)

    May you please provide any data of AD8541/AD8542/AD8544's voltage noise in low frequency? I mean 0.1-10 Hz uV p-p.

    I want to use it for EEG/ECG amplifier: exactly AD8542 - one op-amp for getting reference voltage (Vmid)- for a voltage follower in…

  • Can OPAMP unused pins left open?

    Hi,

    Currently i am using AD8544 for a test circuit to prototype a latching circuit using an Op-Amp. Here is the circuit

    I have wired as per above. 

    Setup: When Vsense is above than Vref, o/p goes high and D2 gets forward biased and this becomes a closed…

  • RE: About the welding temperature(AD series)

    Hi,

    I am currently looking into this. 

    By welding, do you mean soldering? If so, that data can be seen on the Absolute Maximum Ratings of the AD8544.

    I'll get back to you once I have the data for AD8221.

    May I ask why are you trying to know such…

  • RE: AD8541 Large Signal Voltage Gain 's Vs dependency

    Dear Anna

    I beleve in ADI datasheet.

    This Avo feature is changed by Vs drastic.

    So I would like to know changing point.

    Regards

    moto

    Dear Anna Datasheet say "The AD8541/AD8542/AD8544 are optimized to maintain high gains at lower supply voltages…

  • RE: SSM2305 input configured in single ended mode.

    Hello saravanaprabhu,

    I don't handle class d amplifier products but I had some experience on such devices, the main purpose of the coupling capacitor is to remove any dc offset voltage present on the source and only allow the AC signal to pass through.…
