Note 1: Applies to both single supply and split supply operation. Continuous short circuit operation at elevated ambient temperature and/or multiple Op Amp shorts
can result in exceeding the maximum allowed junction temperature of 150˚C. Output currents in excess of ±30 mA over long term may adversely affect reliability.
Note 2: 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)–TAJA.
Note 3: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The
guaranteed specifications apply only for the test conditions listed.
Note 4: Limits are guaranteed by testing or correlation.
Note 5: V+ = 15V, VCM = 7.5V and RL connected to 7.5V. For Sourcing tests, 7.5V ≤ VO ≤ 11.5V. For Sinking tests, 2.5V ≤ VO ≤ 7.5V.
Note 6: V+ = 15V. Connected as Voltage Follower with 10V step input. Number specified is the slower of the positive and negative slew rates.
Note 7: Input referred. V+ = 15V and RL = 100 kΩ connected to V
+/2. Each amp excited in turn with 1 kHz to produce V
O = 13 VPP.
Note 8: A military RETS electrical test specification is available on request. At the time of printing, the LPC660AMJ/883 RETS specification complied fully with the
boldface limits in this column. The LPC660AMJ/883 may also be procured to a Standard Military Drawing specification.
Note 9: For operating at elevated temperatures, the device must be derated based on the thermal resistance
θJA with PD = (TJ–TA)/θJA.
Note 10: All numbers apply for packages soldered directly into a PC board.
Note 11: Do not connect output to V+when V+ is greater than 13V or reliability may be adversely affected.
