• ADG1634 Internal equivalent circuit

    Hi

    I am considering ADG1634.
    Is there any information on the internal equivalent circuit of ADG1634?

  • ADG1634 bipolar supply VDD = +5V and VSS = -10V

    Hi,

    The ADG1634 datasheet specifies "VDD/VSS =±3.3/±8 V min/max" for bipolar supply.

    I am checking if I can operate the ADG1634 with bipolar supply with VDD = +5V and VSS = -10V. Will this violate the ADG1634 specifications and result…

  • ADG1634, THD+N

    Hi!

    I am considering ADG1634.
    I'm interested in the value THD+N. The datasheet says that the value THD+N is 0.3 (page 3), but the graph (figure 24, page 13) shows a smaller value, about 0.27.
    What is the correct value?

    Thank you,

    Andrey.

  • Single supply operation of ADG1634 in LTspice

    ADG 1634 in single supply show low isolation at close to VSS.

    Does it show same performance in real IC ? or just spice model issue?

    I used following conditions.

    simulation bench : LTspiceXVII\examples\jigs\ADG1634.asc

    VDD = 12V, VSS=0V

    Input : SINE(2.5…

  • Pspice model of ADG1634

    HI

    I am considering ADG1634.

    Is there a Pspice model available for the ADG1634?

  • ADG1634通道间信号干扰

         本设计是用于小信号(10mv--100mv)放大,将ADG1634用于差分放大器ADA4938的放大增益配置电阻的选择,获得1倍或10倍的放大增益。在配置是10倍放大的状态下,当只接一路信号时,信号经过放大电路后信号稳定;但是在将另一路信号也接上时,前一路信号的值受到很明显的影响,出现这种现象的原因是什么?还有另一个问题,在配置放大增益为1倍时,只接一路信号时,放大后的信号波动很大,实测达到250mv Vp-p左右,这又是为什么?刚接触模拟电路,知识欠缺,希望前辈能够指点一二。

  • RE: Does the LTspice model of ADG1434 also model the CS/CD (ON/OFF) capacitance?

    Hi, Shubham.

    Regarding device recommendations, the ADG1434 would be a great choice for a compromise between on-resistance and capacitance, as well as packing 4 SPDT switches inside. However, I see from your question in the link above that capacitance…
