1) Power supply
The CXA1100 Series is basically designed to operate on single ended supply. The split supply operation is
also possible, however, VEE (negative) supply should provide low noise and ripple characteristics. The
ripple rejection ratio of these devices is generally good for Vcc supply (single ended supply and split
supply), however, that for VEE supply is not so good in the NR on mode because the integrated capacitors
for the side chain filter are connected to pin 15 (VEE on split supply).
