Hello, I am new in the field of electronics. I am working on a project that contains an IC LM3886 but I am confused about its input current so, can anyone tell me what input current is required for it.
Thanks

Actually I am working on an inverter which contains LM3886 amp so plz tell me what current should I supply with voltage of 24V to get suitable output of 60W??? And my second question is that is it necessary to connect heat sink with LM3886???
