• AD8620

    For an AD8620 with Vs= + -5 volts, is there a graph like the data sheet's Figure 12, "Output Voltage to Supply Rail vs. Resistance Load"?? Figure 12 is for + - 13 V.

  • 请教AD8620

    我想给AD8620正负12v供电,然后驱动ADC7658-1可以吗?

    另外,能否推荐一款仪放:双端输入单端输出、正负12v供电、输入电压范围正负10v,性能可以和AD8620匹配的。

    谢谢

  • 关于ad8620线路接法

    本电路图是功率稳定完整描述图,图中绿色标注部分为接口的相关说明,基本原理就是通过光电二极管采集的电压同设定光强电压做对比,最终将输出电压输送给光栅,以此来调节激光器的光强。

    然而涉及到芯片的一些接法实在不知道原理是什么,因为是从其他控制器直接copy过来的板子,所以不知道有些接法不知道是对是错。

    请教大神描述一下一些接法原理:ad8610的接法网络,tl084, ad823,还有ad712的接法,这些都是为了做什么呢?

    电路图附件表示中。其中ad8610部分在最下方。

  • ad8620 as a current to voltage converter

    I want to convert very low currents in the picoamp range to voltage using the ad8620 opamp. The resistor across the noninverting terminal and the ouput would be in the giga ohm range. Please advise.

  • using AD8620 as cross-coupled single-ended-to-differential converter

    I use AD8620 as a cross-coupled single end to differential coverter as following figure, but it doesn't work. what should I pay attention to? can I use other general OP (such as LF353D) to replace the AD8620? I need +/-12V power supply and both of them…

  • AD8620单端转差分驱动调试问题

    实际应用的电路是AD8620部分,与图中电路一样,应用中发现,输入只能到±7.5V,大于±7.5V后,反相端输出会失真,请大家帮忙看看,这是什么原因?
