Electrical Characteristics at Ta = 25°C, VCC = VS2 = 12 V, VS1 = 5 V, VREF = 2.5 V
Notes: 1. Design guarantee value.
2. The MUTE1, and MUTE2 pins turn the output on when high and off when low. When the output is off, the outputs will be in the high-impedance
state.
The figure below shows the relationship between the channels and the MUTE pins and between the channels and the power supplies.
