Good afternoon,
I've recently incorporated the AD8229 part into a prototype design, we are using this part in several places. I was a bit shocked when I saw the commercial part was priced at $220 per part. Needless to say, I'm looking for alternatives…
I have been using the Analog Devices version of Multisim for a while and just downloaded version 12. I modeled a simple amplifier using the AD8429.
Signal on the negative input, positive input grounded, +/-15V, gain resistor of 60.4 ohms for a gain of…
A little more information for other people facing a similar problem. I was able to get my output noise measurement down to 162 nV/rtHz ( I had some extra resistance at the input that wasnt exactly matching the circuit above).
I also noticed the datasheet…

A few extra comments:
- The RG noise is actually scaled by (Gain -1)/Gain in the equation Scott gave and in the AD8229 datasheet. For most gains, this is inconsequential, but if you are doing calculations at very low gains, this can matter. This is why…
Percy,
I would use an Instrumentation Amp with a stable 1V on one side. Look at AD8421, AD8428, AD8229, or AD8226.

您好！
ADI具有宽带宽的仪放产品，您可以看一下AD8251，AD8253，AD8229，AD8429。
Two other in-amps that come close to enough bandwidth are the AD8229 and AD8429. Gain of these parts is set by an external resistor.
ADI有工作于210deg环境下芯片，例如仪表放大器AD8229，A/D转换AD7981等，供电有高温电池
