输入阻抗(inputimpedance)主要是电路输入端的等效阻抗。如果我们在输入端加一个电压源U并在输入端测量电流I,则输入阻抗Rin为U/I。输入端可以被认为是一个电阻的两端,这个电阻的阻值就是 2022-12-27 17:27:09 输出阻抗与输入阻抗的区别是什么 有关输入阻抗的概念,阻抗是电路或设备对交流电流的阻力,输入阻抗是在...
输入阻抗输入阻抗(input impedance)是指一个电路输入端的等效阻抗。在输入端上加上一个电压源U,测量输入端的电流I,则输入阻抗Rin就是U/I。你可以把输入端想象成一个电阻的两端,这个 2022-12-27 11:38:34 输入阻抗和输入电容 下图1 形象的说明了运放的输入端阻抗的特性。主要有两个参数,输入阻抗和输入电容。

7. 输入阻抗(Input Impedance):输入阻抗是指ADC对输入信号的阻抗。输入阻抗越高,ADC对外部电路的影响就越小。 8. 速度(Speed):ADC的速度是指该设备每秒钟能够完成的转换次数。速度越高,ADC响应的时间越短。 二、ADC电路形式: 1. 逐次逼近型ADC(Successive Approximation ADC):逐次逼近型ADC是一种常用且成熟的AD...
There is no specific information about the input impedance of the ADC Alt ref pins after the Aurix TC387 loses power. However, we can make an educated guess based on the general behavior of ADC inputs. In most cases, when a microcontroller loses power, its input pins will be in a ...
which enables a longer acquisition phase as shown in Figure 3. The nonlinear kickback seen from this ADC family input is significantly reduced even with high-input impedance (Z) mode disabled and it is reduced to almost negligible levels when high-Z mode is enabled. This redu...
Guys, I have searched the reference manual but cannot find the input impedance of the ADC pins. Where in this document is the pad information available? Thanks, Nick Labels: General 0 Kudos Reply All forum topics Previous Topic Next Topic 1 Reply ...
from input to output. Consequently, the load impedance should always be the same as the input ...
