可以看一下AD8616 AD8618， 偏流也很小
AD7699引起的毛刺是正常现象, 不能完全消除, 它不会影响转换结果.
The schematics as published in the article on EDN shows the power connection of the AD8618 at the source of the MOSFETs (output ORed node). The AD8619 is a quad op-amp, so only 1 power connection is shown.
In the case you want to use 4 single op-amps…
Actually, input bias current is another criteria for our application(tens of nano Amp or less is allowable), so that is the reason why I thought AD8652 or AD8618 will work for my application. As per your recommendation, ADA4807-2 is great…
A quad is not four op amps in one package, it is four functions in one piece of silicon. At high
frequencies, you have coupling with stray C to substrate, through the bond wires, between
the traces on the pc board, etc. If you have capacitance…
I'm still relatively inexperienced with circuit design and I am wondering if I am misunderstanding something fundamental about this particular op amp. The AD8615 series is a single supply op amp, but one of the listed application is photodiode preamplification…
I want to achieve the best linearity possible from the AD5791B at low frequencies, below 1k Hz, but I'm concerned about the buffer amp performance.
The AD8675 is recommended for the output buffer but it's minimum CMRR spec is only 114dB which equates…
