• AD8622: macro model is for +/-15V supply only, Have you got a macro model for AD8622 for +/-2.5V supply voltage operation?

    Have you got a macro model for AD8622 for +/-2.5V supply voltage operation?
    For Vs=+/-5V it works fine but it doesn’t work with +/-2.5V. 


    Our SPICE models are usually created for the higher supply voltage of the op
    amp (mentioned in…
  • PSRR of AD8622

    On pages 3/4 of the data sheet, a minimum PSRR of 125 dB @ 25°C is specified,
    whereas in Figs. 29/32 the PSRR apparently settles to slightly above 100 dB
    below 10 Hz. Could you please explain the reason for this discrepancy?

  • AD8622 spice model output current at zero input


    My test circuit is very simple: non inverter amp, gain 2, 500 ohms resistors .Input is 1uV(for test).I measured Vout ~-1mV .The input bias current was measured to be ~300p, but the output current  was ~1.2uA, so it is the reason to the -1mV output…

  • AD8622使用

    在使用ad8622 构成仪表放大的时候,当输入端悬空什么都不接的时候,输出端是电源电压,因为用这个仪表放大测量脑电信号,当接到人体的时候,因为第一级仪表放大只有10倍,脑电信号5-

  • Can AD8221BR, AD8622 improve current design?

    We are redesigning a test board due to heating in a few LT1167 (LT1167ACS8) and LT1352 (LT1352CS8) devices. Due to lack of information on the specific devices that heat up, done LT Spice simulation for circuits, and have nearly narrowed down on the problem…
