Notes:
1. Excludes bias and modulation currents.
2. Bias and modulation currents add directly to power supply current in 5V applications. The additional supply current noted excludes these currents.
3. V_CC3 “supply OK” circuitry monitors the internally regulated 3.3V supply when V_CC = 5V (VCC3_SEL =low).
monitors V_CC (VCC3_SEL =high).
4. A low level at IBOUT_CA does not trigger a fault condition during common cathode operation.
5. A low level at IBOUT_CC does not trigger a fault condition during common anode operation.
When V_CC = 3.3V, V_CC3 “supply OK” circuitry
