Notes : 1. For suppl y voltages l ess than ±15V, the absolute maximum input vol tage is equal to the supply vol tage.
2. Any of the amplifier outputs can be shorted to ground indefinitly ; however more than one should not be
simultaneously shorted as the maximum junction temperature will be exceeded.
