EVALUATION FIXTURE
FEATURES
DESCRIPTION
● EASY AND FAST PERFORMANCE TESTING
● SHOWS OPTIMIZED BOARD LAYOUT
● REPLACES SELF-MADE BOARDS
The demo fixture DEM-OPA660-1GC allows easy and
fast performance testing of the OPA660AP building
blocks OTA and buffer stage. Figure 1 shows a diagram
of the test fixture, and Figures 2, 3 and 4 show the
frequency responses of the OTA stage measured at
gains 1, 2, and 10 with various output levels from
0.2Vp-p to 5Vp-p.
APPLICATIONS
● COMPONENTS INCOME CONTROL
● PERFORMANCE CHECKS
● CIRCUIT DESIGNS
Figure 5 illustrates the frequency response of the buffer
stage. The silk-screen and the double-sided layout can
be seen in Figure 6.
