Note 1: Operation is guaranteed up to 60V, however, distortion may be introduced from SPiKe Protection Circuitry if proper thermal considerations are not taken
into account. Refer to the Application Information section for a complete explanation.
Note 2: DC Electrical Test; Refer to Test Circuit #1.
Note 3: AC Electrical Test; Refer to Test Circuit #2.
Note 4: All voltages are measured with respect to the GND pins (5, 10), unless otherwise specified.
Note 5: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which
guarantee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit
is given, however, the typical value is a good indication of device performance.
Note 6: For operating at case temperatures above 25C, the device must be derated based on a 150C maximum junction temperature and a thermal resistance
of
θJC = 1C/W (junction to case) for the T package. Refer to the section Determining the Correct Heat Sink in the Application Information section.
Note 7: Human body model, 100pF discharged through a 1.5k
resistor.
Note 8: The operating junction temperature maximum is 150C, however, the instantaneous Safe Operating Area temperature is 250C.
Note 9: Typicals are measured at 25C and represent the parametric norm.
Note 10: Limits are guarantees that all parts are tested in production to meet the stated values.
Note 11: VEE must have at least 9V at its pin with reference to ground in order for the under-voltage protection circuitry to be disabled. In addition, the voltage
differential between VCC and VEE must be greater than 14V.
Note 12: The output dropout voltage, VOD, is the supply voltage minus the clipping voltage. Refer to the Clipping Voltage vs. Supply Voltage graph in the Typical
Performance Characteristics section.
Note 13: When using the isolated package (TF), the
θJC is 2C/W verses 1C/W for the non-isolated package (T). This increased thermal resistance from junction
to case requires a lower supply voltage for decreased power dissipation within the package. Voltages higher than ±26V maybe used but will require a heat sink with
less than 1C/W thermal resistance to avoid activating thermal shutdown during normal operation.
