V+ and V- (±5V to ±3V) are the amplifier power supplies. The amplifiers are specified with dual power supplies. VCC and VSS
is the logic supply. All ratings are over the temperature range for the Industrial (-40 to + 85°C) and Commercial (0 to 70°C)
versions of the part unless specified differently.
