hello everyone：
好吧，刚才有这个疑惑，但是仔细看了看，明白怎么回事了，写出来分享一下。
我在阅读AD8007的datasheet时，想查看AD8007的输出电压范围，也就是Output Voltage Range，但是读到一个参数Output Saturation Voltage。
请看下面的数据：
Output Saturation Voltage的字面意思是输出饱和电压。第一眼看到这个数据，给我的感觉是AD8007在VS=+/-5V的时候，Output Saturation…
您好， 您可以考虑以下芯片：
ADA4817,ADA4891,AD8045,AD8011,ADA4350,ADA4932,AD8099,ADA4930,
ADA4927,AD8009,ADA4939,AD829,ADA4940,AD8065,AD8007,AD8001,ADA4851
There's plenty on offer from Analog Devices, so I suggest you look at the AD8010, AD8009 and AD8007. Most modern parts are short circuit protected, but you'll need to check the datasheets.

if say so, using of large 22u to 47u caps as ac coupling for the output of high speed op-amps such as ad8067 or ad8007/8009 have no problem, right?
I have yet to see any applications where current mode op-amps (AD8007) were used in 4 resistor diff amp configurations.
Can they be used that way? What are the differences in performance between CF and VF amps in this configuration?
I would assume that…
Hello serhiy,
I didn't write the AD8007/8 data sheet, but I believe I can shed some light on what's going on here. Problems are often encountered when applying RF specifications to op-amps and differential amps since RF systems typically operate in fixed…
hi tsmith7,
The ADA4932 and AD8007 have operating frequencies lower than 400MHz at large signal (2Vpp). Since you need 1Vpp and it was not specified in the data sheet, there's no guarantee that the frequency at 1Vpp will have exactly or more than 400MHz…
OK I write it again here about the whole schematic...
I plane to use AD8009 or AD8007 as last stage buffer of my analog front end circuit before AD8302.
before AD8009 I have a resistive Attenuator, one AD4817 as a High Speed FET input buffer and a AD8337…
Dear Gauzz
Thank you for the reply.
the load that I said before is input of AD8302 and its input ac coupled capacitor.
yes 47u seems too large. I plan to use AD8302 in a wide frequency range from 20Hz to 50Mhz.
I plane to use AD8009 or AD8007 as last…
Tanq for the reply
