IL = 100 mA
IL = 0 to 200 mA
VCC = 6 to 12 V, IL = 100 mA
Notes:1. The total current drain for VCC1 and VCC2 with no load.
2. The voltage across an 8 Ω load. With the output saturated.
3. MUTE: When the MUTE pin is high, the outputs will be on, and when low, off (high impedance)
4. These values are design guarantee values, and are not tested.
