Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and test conditions, see the Electrical Characteristics. Note 2: Human Body Model, applicable std. MIL-STD-883, Method 3015.7. Machine Model, applicable std.

The maximum allowable power dissipation at any ambient temperature is P = (T – J(MAX) JA D J(MAX) T )/ θ . All numbers apply for packages soldered directly onto a PC Board. A JA Note 4: Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not guaranteed on shipped production material. Note 5: Limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed through correlations using statistical quality control (SQC) method. www.national.com 4 Document Outline LMP2015 Single/LMP2016 Dual General Description Features Applications Connection Diagrams Ordering Information Absolute Maximum Ratings Operating Ratings 2.7V DC Electrical Characteristics 2.7V AC Electrical Characteristics 5V DC Electrical Characteristics 5V AC Electrical Characteristics Typical Performance Characteristics Application Information THE BENEFITS OF THE LMP2015/LMP2016'sNO 1/f NOISE OVERLOAD RECOVERY FIGURE 1.
