| MICROCIRCUIT DATA SHEET MDLM143-X REV 0A0 HIGH VOLTAGE OPERATIONAL AMPLIFIER General Description The LM143 is a general purpose high voltage operational amplifier featuring operation to +40V, complete input overvoltage protection up to +40V and input currents comparable to those of other super-B op amps. Increased slew rate, together with higher common-mode and supply rejection, insure improved performance at high supply voltages. Operating characteristics, in particular supply current, slew rate and gain, are virtually independent of supply voltage and temperature. Furthermore, gain is unaffected by output loading at high supply voltages due to thermal symmetry on the die. The LM143 is pin compatible with general purpose op amps and has offset null capability. Application areas include those of general purpose op amps, but can be extended to higher voltages and higher output power when externally boosted. For example, when used in audio power applications, the LM143 provides a power bandwidth that covers the entire audio spectrum. In addition, the LM143 can be reliably operated in environments with large overvoltage spikes on the power supplies, where other internally-compensated op amps would suffer catastrophic failures.

Operating Ratings indicate conditions for which the device is 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. Some performance characteristics may degrade when the device is not operated under the listed test conditions. The maximum power dissipation must be derated at elevated temperatures and is dictated by Tjmax (maximum junction temperature), ThetaJA (package junction to ambient thermal resistance), and TA (ambient temperature ). The maximum allowable power dissipation at any temperature is Pdmax - (Tjmax - TA)/ThetaJA or the number given in the Absolute Maximum Ratings, whichever is lower. For supply voltage less than +40V, the absolute maximum input voltage is equal to the supply voltage. Human body model, 1.5K Ohms in series with 100pF.
