STANDBY
Standby Current
1)
No input signal, Vstdby = Vcc, RL = 8
1. Standby mode is actived when Vstdby is tied to Gnd
2. Dynamic measurements - 20*log(rms(Vout)/rms(Vripple)). Vripple is an added sinus signal to Vcc @ F = 217Hz
3. Dynamic measurements - 20*log(rms(Vout)/rms(Vripple)). Vripple is an added sinus signal to Vcc @ F = 217Hz
