MAX40660 TIA的DC耦合和AC耦合的区别。（Difference between DC-coupling and AC-coupling for the MAX40660 TIA）

Question

MAX40660手册中给出了DC耦合和AC耦合的两种电路构型，请问在实际应用中，这两者各自有什么优劣，我该如何选择。 
 The MAX40660 manual gives two circuit configurations, DC-coupled and AC-coupled, what are the advantages and disadvantages of each and how do I choose between them in practical applications.

参考MAX40662 datasheet。 
 &ldquo; 
 AC or DC-Coupling on Input Coupling choice of electrical signal from APD to the TIA is a major design decision a system designer has to make based on the trade-offs. The DC-coupled input design, as shown in Figure 1, is the least complicated and takes minimum number of components that serves best in saving PCB space and cost. In DC-coupled mode, input channel switching times are rapid on the order of ​​。。。。
