Notes:
1. Source voltage to ground when an 8 Ω load is connected between bridge amplifier outputs.
2. Sink voltage to ground when an 8 Ω load is connected between bridge amplifier outputs.
3. When the mute signal is high, all amplifier outputs turn on, and when low, all amplifier outputs turn off. When the mute
signal is low, amplifier output is undefined.
4. 5 V supply voltage when the reset output goes low.
5. Potential difference from the 5 V supply voltage when the reset output goes low and when it goes high.
