Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics Tables. Note 2: Human Body Model is 1.5 kΩ in series with 100 pF. Machine Model is 0Ω in series with 200 pF. Note 3: 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) -T A)/θJA . All numbers apply for packages soldered directly onto a PC board. Note 4: Electrical table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of the device. Note 5: Typical values represent the most likely parametric norm at the time of characterization. Note 6: Limits are 100% production tested at 25˚C. Limits over the operating temperature range are guaranteed through correlations using the Statistical Quality Control (SQC) method. Note 7: Offset voltage average drift is determined by dividing the change in VOS at the temperature extremes into the total temperature change. Note 8: Positive current corresponds to current flowing into the device. Note 9: Input bias current is guaranteed by design. Note 10: The device is short circuit protected and can source or sink its limit currents continuously. However, care should be taken such that when the output is driving short circuit currents, the inputs do not see more than±0.3V differential voltage. Note 11: Slew rate is the average of the rising and falling slew rates. Connection Diagram 5-Pin SOT23 20120301 Top View
