all of the transient current is delivered to the slewing (TZ) node (Pin 5) via a short signal path (the grounded base stages and the wideband current mirrors).
The current available to charge the capacitance (about 4.5 pF) at the TZ node is always proportional to the input error current, and the slew rate limitations associated with the large signal response of the op amps do not occur.
大家好:
我想如上图用 AD844 搭建一个恒流源,但我始终不明白 Pin5 TZ 脚是什么意思?为什么接到负载是由 TZ 脚输出而不是由 Pin6 OUT 脚输出?
上面的英文是手册里面第 14 页的一段关于 TZ 脚的解释,能否帮我看一下文字的意思为何?谢谢。
