The most suitable front-end amplifiers for this type of application are amplifiers like the ADA4610-1, ADA4610-2, or AD8605, AD8606. These amplifiers provide a low noise option which makes them suitable for use in signal chains using low noise ADC…
There is quite a choice available, and you haven't mentioned speed.
The ADA4610 looks like it's worth a look as it can output 70mA and typical drift is only 0.5uV/C
in fact I will be mostly using it for DC measurements, ADA4622-2, ADA4610-2 seem to have large offset, ADA4000-2 even bigger.
我最关注的是算是能源领域。最喜欢用的就是ADI的高精度运放和ADC比如这几款都有用过ADA4610-1 ADA4896-2 AD8432 AD7091 AD9484 实在太棒了
Regarding a JFET follower before the AD8129 to reduce AD8129 input bias current induced noise:
I assume you have a DC coupled signal path.
To implement such a discrete JFET buffer when you're DC coupled, I think you'd have to get creative with…
Good Day. In the specification you have listed, I could advice you to choose from ADA4177-1 , ADA4610-1 or AD8510. All them could perform on your specified requirements. It could tolerate your common-mode voltage of 0.5 to 0.75V, it can also have…
Is there an issue with the AD8610 spice model?
When I compare the ADA4610, AD8625 and AD8610, the output (Vout3) of the 8610 is heavily dependent on the input resistor R14.
For 1K or higher the output goes to the -rail.
This occurs when using +- 10V…
24V times 7.5mA times 2 is about 0.4 Wts, so sounds reasonable
Although it might be oscillating. Put a scope on the outputs.
I would drop your 6.8k and 100k by a factor of ten for lower noise.
Depending on highest frequency, load, etc., you could look…
Upon checking on different datasheets, I think that ADA4610-4 would be a good replacement for LM837. With the same package, performance and function. It also have a lower THD+N value of 0.00025% compared to LM837 which has 0.0015. It also meets…
