Description
Analog Ground
Logic output. When low, indicates that the level of the input signal has
overloaded the amplifier.
Positive 5 Volts
Logic input. When high, both amplifiers are muted. When low (grounded), both
amplifiers are fully operational.
Single-ended input (Channel 1 & 2)
Break-before-make timing control
Kelvin connection to speaker ground (Channel 1 & 2)
Over-current threshold adjustment (Channel 1 & 2)
Over Current Sense resistor, Channel 1 low-side
Over Current Sense resistor, Channel 1 high-side
Kelvin connection to source of low-side transistor (Channel 1 & 2)
Feedback (Channel 1 & 2)
Voltage: +12 V from V_SNEG. Refer to Application Information section.
Low side gate drive output (Channel 1 & 2)
Kelvin connection to source of high-side transistor (Channel 1 & 2)
High side gate drive output (Channel 1 & 2)
Positive supply voltage
Negative supply voltage
Power Ground
Over Current Sense resistor, Channel 2 low-side
Over Current Sense resistor, Channel 2 high-side
Logic output. When high, indicates that the output stages of both amplifiers
are shut off and muted.
Not Connected - Must Be Left Floating
