Auto zero amplifiers,like opa2188 ,have spike bias current which is very huge.The datasheet of AD8628 did not mention spike bias current,does AD8628 have very low spike bias current or it does not have any spike bias current?

Hi,
What series resistor value did you add? Can you attach your circuit for better understanding including the voltage input and power supplies values? Thanks.
Hi Harry,
Thank your for your reply. The AD8628 was in fact my second option for the filter. I only went to the ADA4528-1 because it was cheaper than the AD8628 in 3 of 4 distributors. Also, although on paper every calculation seemed ok, I got weir results…
你好，我看AD8628的文档说AD8628是单电源供电，但是在AD5512A的文档里，说AD5512A的双极性输出操作是，给出的例子里用的就是AD8628，但是图里面是接的确实双电源，如下图
我使用的AD5512A的双极性输出，那应该是5v单电源，还是双电源+-5V？谢谢
We are attempting to use an AD8630 to amplify the signals from four thermopiles. This amplifier was recommended by Dexter Research, a thermopile manufacturer. One thermopile is equipped with broad-band optical window which admits a lot of light, and the…
Yes the DAC could become unstable as we have not characterised the amplifier beyond this. The lowest resistive load is 5K.
You could investigate the use of the AD5066(Unbuffered version of the AD5064) and an external low-noise low-offset op-amp…
Looking at Figure 11 (Ouput Voltage to Supply Rail vs. Load Current) of the AD8628 datasheet it can be seen that you can get up to 10 mA at the expense of about 400mV drop from the supply rail.
From Figure 15 of ADA4528-1 it seems that you can get…
