These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Refer to RETS146X for LM146J military specifications. (2) For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage. (3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (4) The maximum power dissipation for these devices must be derated at elevated temperatures and is dictated by TjMAX, θjA, and the ambient temperature, TA. The maximum available power dissipation at any temperature is Pd=(TjMAX - TA)/θjA or the 25°C PdMAX, whichever is less. (5) Any of the amplifier outputs can be shorted to ground indefinitely; however, more than one should not be simultaneously shorted as the maximum junction temperature will be exceeded. 2 Submit Documentation Feedback Copyright © 2004, Texas Instruments Incorporated Product Folder Links: LM146 LM346 Document Outline FEATURES DESCRIPTION Connection Diagram Capacitorless Active Filters (Basic Circuit) ABSOLUTE MAXIMUM RATINGS DC ELECTRICAL CHARACTERISTICS DC ELECTRICAL CHARACTERISTIC DC ELECTRICAL CHARACTERISTICS TYPICAL PERFORMANCE CHARACTERISTICS APPLICATION HINTS COMMON-MODE INPUT VOLTAGE OUTPUT VOLTAGE SWING VS ISET INPUT CAPACITANCE TEMPERATURE EFFECT ON THE GBW ISOLATION BETWEEN AMPLIFIERS LM146 TYPICAL PERFORMANCE SUMMARY SPEED VS POWER CONSUMPTION Typical Applications Active Filters Applications Circuit Synthesis Equations Circuit Synthesis Equations Miscellaneous Applications Schematic Diagram
