Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics Table.
Note 2: Human Body Model is 1.5 k
Ω in series with 100 pF. Machine Model is 0Ω in series with 200 pF.
Note 3: If the input-output voltage differential exceeds ±5V, internal clamping diodes will turn on. The current through these diodes should be limited to 5 mA max.
Thus for an input voltage of ±15V and the output shorted to ground, a minimum of 2 k
Ω should be placed in series with the input.
Note 4: The maximum continuous current must be limited to 300 mA. See the Application section for more details.
Note 5: For the condition where the CL pin is left open the output current should not be continuous, but instead, should be limited to low duty cycle pulse mode such
that the RMS output current is less than or equal to 300 mA.
Note 6: Soldered to PC board with copper foot print equal to DAP size. Natural convection (no air flow). Board material is FR-4.
Note 7: VIN = + or −4V at TJ = −40˚C.
Note 8: The maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is
PD =TJ(MAX)–TA)/θJA. See Thermal Management section of the Application Hints.
