I'm trying to incorporate ADA4004 in my next audio design as a low power replacement of OPA1612. Is there any data on its THD?
数据手册上ADA4004-1/ADA4004-2/ADA4004-4的数据手册，静态电流写的是每个放大器电源电流是2 mA。我想确认一下，这里是说每个通道还是指的整个运放。比如说对于四通道的ADA4004-4，其功耗应该是2 mA*Vdd*2还是2 mA*4*Vdd*2？
OK, thanks - I was planning to use the ADA4004 amplifier (http://www.analog.com/static/imported-files/data_sheets/ADA4004-1_4004-2_4004-4.pdf), which I guess could conveniently produce an output current of up to around 1mA. What capacitance would be needed…
You may want to used the ADA4898-1, AD8597 and ADA4004-1. These are low noise/distortion amplifiers that are unity gain stable and capable to handle your required supply voltage.
I hope this helps!

Can the AD797 be used as a non-inverting buffer? I followed the circuit guidance in the data-sheet (figure 37), but the circuit is oscillating at about 900 KHz. Table 6 on the data sheet lists the recommended circuit values for the follower circuit, but…
Recently I had a full board using, among others, the chips named above. As I got ADA4004 or ADG1436 burnt without any explanation, I did a prototype board using only the above chips to try to discover the problem and still have the same problem…
All this time I was looking at the Filter Wizard, assuming you were talking about the graphs the
tool generated with the OP281 and the ADA4004. Did you actually build some hardware
and look at it on the bench?
