| MICROCIRCUIT DATA SHEET MNLMC6462AM-X REV 1A1 Original Creation Date: 04/03/96 Last Update Date: 05/19/98 Last Major Revision Date: 02/09/98 PRECISION CMOS DUAL MICROPOWER OPERATIONAL AMPLIFIER General Description The LMC6462 is a dual low offset voltage amplifier, combining rail-to-rail Input and Output Range with very low power consumption. Performance characteristics include low input bias current, high voltage gain, rail-to-rail output swing, and an input common mode voltage range that exceeds both rails, operating at 3V, 5V, and 15V. The rail-to-rail output swing of the amplifier, for loads down to 25 KOhms, assures maximum dynamic signal range. These features, plus its low power consumption, make the LMC6462 ideally suited for battery powered applications. The LMC6462 is an excellent upgrade for circuits using limited common-mode range amplifiers. For designs that require higher speed, see the LMC6482 dual operational amplifier.

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. Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150 C. Output currents in excess of +30mA over long term may adversely affect reliability. Human body model, 1.5k Ohms in series with 100pF. Do not connect output to V+, when V+ is greater than 13V or reliability will be adversely affected. Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings. All numbers apply for packages soldered directly into a PC board.
