VOF1 to VOF3 Voltage differential between the channel U and W outputs
VIN
Voltage range for VIN1 to VIN3
VBUFFER1 Voltage difference relative to 1/2 VS1
VBUFFER2 Voltage difference relative to 1/2 VS2
VO1
Output high, IO = 700 mA, all + outputs
VO2
Output low, IO = 700 mA, all + outputs

SR
Mute on voltage
The voltage applied to MUTE1 or MUTE2 at the point
VMUTE1, 2 where the output goes on.
Mute on current
The influx current to MUTE1 or MUTE2 at the point
IMUTE1, 2 where the output goes on.
Notes: 1. When MUTE1 is high, the channel U output will be on.
2. When MUTE2 is high, the channel V and W outputs will be on.
