2 Proposed Topologies

As previously mentioned, analog TGC (ATGC) circuits need to be designed to meet a variety of requirements, such as noise performance, level requirements, control accuracy requirements, and so forth. Thus, to meet different needs of customers and help them to complete the design, TI offers three different TGC designs that engineers can comprehensively evaluate based on the number of channels, noise performance requirements, and cost of their own products, and then choose the appropriate ATGC driver circuit for their needs. There are multiple approaches for a TGC control circuit that are based on the type of DAC.
