  • OP295 SUPPLY CURRENT Distribution

    Mochi
    Mochi

    I read Datasheet of OP295.

    Figure 5. is Supply Current Per Amplifier vs. Temperature.

    Figure 8. is OP295 Input Offset (VOS) Distribution.

    About Supply Current Per Amplifier , Is there a similar histogram?

    Please show me the histogram, if possible…

    Hello,

    which are the preferred values for the input and feedback resistors for an OP285 amplifier in inverting/non inverting configuration?

    The absolute gain would be 1 (a buffer) or maximum 2 (non inverting config.).

    Thank you in advance

  • DA输出经运放OP295调节后纹波很大

    最近在整的一个电路中,一个DA模块,DA芯片选的是4路八位的AD7305,从AD7305输出的模拟电压没什么问题,但经过op295运放调节输出后,纹波变得非常之大,就算7305输出0V的情况下也是一样非常大的纹波,大概1000mv的,几千hz的波形,麻烦各位大侠看看我的电路是不是有什么问题!具体的运放调节计算公式在图中,Vin来自AD7305的其中一个模拟电压输出端。也顺便看看这样计算有没有问题。谢谢啦。

  • The concept of Large signal voltage gain 's measurement condition ?

    moto

    Hi

    I would like to know how to decide the condition of "Large signal voltage gain".

    For example, AD8542's condition is

    Vs=2.7V VCM=1.35V

        RL=100Kohm Vo=0.5 to 2.2V

    Vs=5V VCM=2.5V

        RL=100Kohm Vo=0.5 to 2.2V

    How to decide this vo condition…

    jr,

      You can also look at fig 26 on the OP295 datasheet:

    http://www.analog.com/static/imported-files/data_sheets/OP295_495.pdf

    You can take that basic idea with an ADA4051-1 and an ADR280 and come up with a good design.

    You mentioned "ADR820";…
