Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.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.

Note 2: 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.

Note 3: Applies to both single-supply and split-supply operation. Continous 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.

Note 4: Do not connect output to V+, when V+ is greater than 13V or reliability will be adversely affected.

Note 5: Human body model, 1.5k ohms in series with 100pF.

Note 6: All numbers apply for packages soldered directly into a PC board.

The 6461 is a precision dual low offset voltage, micropower operational amplifier,capable of precision single supply operation. Performance characteristics include ultra low input bias current, high voltage gain, rail-to-rail output swing, and an input common mode voltage range that includes ground. These features, plus its low power consumption,make the 6461 ideally suited for battery powered applications.

Other applications using the 6461 include precision fullwave rectifiers, integrators,references, sample-and-hold circuits, and true instrumental amplifiers.

The 6461 is built with National's advanced double-Poly Silicon-Gate CMOS process.
