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

…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…
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。
用multisim仿真使用OP295反馈电路时，如何使用波特仪测量增益和相位特性曲线？为什么我用波特仪画出的增益特性曲线一直是负的几十dB与实际情况完去不附啊！求助大神！像上面图片所示
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";…
