• ADR435 Short-Circuit

    Dear Analog Devices

     

    I am reading the datasheet and just wanted to be 100% sure that do I understand the "Indefinite" correctly?

    Do I understand correctly that the ADR435 won’t be damaged if the output is shorted to GND?

  • ADR435 Spice model

    Hi,

    I need spice model of the ADR435 voltage reference IC. 

    I mainly required it to simulate the effect of RC network on the COMP pin. 

    Could you please provide me the Spice model for this part.

    Regards,

  • Cumulative Error calculation for a voltage reference - ADR435

    Hi,

    I am using ADR435 as a reference for a 18 Bit ADC(AD7631). The specification demands a detailed calculation of error introduced by the reference. I have done the error analysis in following way. Please confirm that the calculations are correct and…

  • When the ADR435 input voltage less then 7.0V

    I really want to know the minimum input voltage Fengyun ADR435ARMZ? (I need 7.0 volts below the estimated base on the characteristics of the internal circuit design)

    Can someone give me some calculation or help?

  • CN0032电路笔记中,ADA4941-1可否用+9V和-5V供电,并且ADR435也为+9V供电

    CN0032电路笔记中,ADA4941-1可否用+9V和-5V供电,并且ADR435也为+9V供电

    电路笔记中写道。“只要ADA4941-1上的绝对最大值总电源电压不超过12 V,并且满足ADR435的裕量要求,则也可以使用其它电压。”

    是不是说,正电源电压绝对值加负电源电压最大值,不能超过12V?还是说正的不能超过12V,负的不能小于-12V?因为想用固定值的三端稳压电源供电,所以,是不是ADA4941-1用+6V供电,和-5V供电的话也可以满足要求?

  • RE: Noise reduction for negative reference

    Dear Harry,

    the ADR435 has 0,1-10Hz noise of 4uV compared to 8uV of the ADR435- but with only 5V output, so I have to amplify twice as much (also the noise). The ADR noise density of abt. 60 uV/sqrt(Hz) @ 100Hz to me also appears worse than the 100uV…

  • RE: AD620, digitally adjusted reference pin

    Hi DC,

    For the reference IC, I would recommend ADR435 which has an output voltage of 5V, output accuracy of +/- 2mV (B grade) and a temperature coefficient of 3ppm/C. It has a wide operating range (7V to 18V) and would suit your design perfectly as you…

    Hi codigwe,

    Seems you follow the recommended setting for the reference circuit.It should be able to power the ADR435 with a  +15V supply. . Aside from ADAS3022 and ADR435 what other components connected to this? it draw current if the total impedance excess…
