AD824输出至轨还有2V的余度,可以通过什么样的外部连接缩短这个范围吗?使其尽量至轨,比如3V供电,输出只能达到1V,想要其接近3V
Hi Akira,
I had a quick run of AD8657 and AD824 DC parameters on LTSPICE, both offset voltage are within the datasheet spec which is 350uV for AD8657 and 100uV for AD824.
Please see below for my test setup and simulation results.
We usually model and…
Josh,
I forgot to add that the OP400 product page does point out that the AD824, a much newer part, might be a better choice.

Q1. What is the ADA4622-4 / ADA4622-2 / ADA4622-1?
A1. The ADA4622-4 / ADA4622-2 / ADA4622-1 is the next generation of the AD824 / AD822 / AD820. It is a single supply, 30 V, 8 MHz, Low Bias Current, Single-Supply, RRO, Precision JFET Op Amp.

绝大多数的模拟电路设计者都知道怎么在双电源电压的条件下使用运算放大器,比如图1左边的那个电路,一个双电源是由一个正电源和一个相等电压的负电源组成。一般是正负15V,正负12V和正负5V也是经常使用的。输入电压和输出电压都是参考地给出的,还包括正负电压的摆动幅度极限Vom以及最大输出摆幅。
单电源供电的电路(图1中右)运放的电源脚连接到正电源和地。正电源引脚接到VCC+,地或者VCC-引脚连接到GND。将正电压分成一半后的电压作为虚地接到运放的输入引脚上,这时运放的输出电压也是该虚地电压…
