EVALUATION FIXTURE  
FEATURES  
DESCRIPTION  
● EASY AND FAST PERFORMANCE  
The Demo Fixture DEM-OPA660-3GC allows easy  
and fast performance testing of the OPA660AP build-  
ing blocks OTA and buffer stage in the direct-feed-  
back amplifier configuration. Figure 1 shows the dia-  
gram of the test fixture, while Figure 2 illustrates the  
silk-screen and double-sided layout.  
TESTING  
● SHOWS OPTIMIZED BOARD LAYOUT  
● REPLACES SELF-MADE BOARDS  
The frequency response can be seen in Figure 3.  
Figure 4 illlustrates the test configuration.
