Notes on Applications
1) Power supply
The CXA1100 Series is basically designed to operate on single ended supply. The split supply operation is
also possible, however, V
ripple rejection ratio of these devices is generally good for Vcc supply (single ended supply and split
supply), however, that for V
for the side chain filter are connected to pin 15 (V
