I'm a DFAE in Japanese disty.
Our customer is using a part of AD8436 as attached inverting amplifier.
<Q1>: Is it no problem to use it as an operation amplifier?
If the answer to Q1 is "no problem" , please also take care Q2 below.
The attached schematic amplifies input voltage to about -10.7 times. 300mV input is amplified to -3.2V.
However, some AD8346 have a bit big Vout fluctuation as rising room temperature. Normally Vout fluctuates about 2%, -3.2V at Ta=25 degC, -3.14V at Ta=60 degC
Some AD8346 have about 5%, they output -3.05V at Ta=60 degC.
<Q2>: As for the schematic, is there any way to lower such Vout fluctuation caused Ta rising
