• ### OP295 inverting/non inverting amplifier

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.).

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…

### Q

What is the percentage of tin contained in the termination lead plating for
the OP295GS? I need to know what tin / lead combination is.

### A

For the OP295GS, the lead finish is Sn 85%, Pb 15%

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

Hi

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

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:

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

考考你——是先滤波再放大，还是先放大再滤波？
