The maximum safe power dissipation for the AD8273 is limited Parameter Rating by the associated rise in junction temperature (T Supply Voltage ±18 V J) on the die. At approximately 150°C, which is the glass transition temperature, Output Short-Circuit Current Observe derating curve the plastic changes its properties. Even temporarily exceeding Voltage at Any Input Pin 40 V this temperature limit may change the stresses that the package Differential Input Voltage 40 V exerts on the die, permanently shifting the parametric performance Current into Any Input Pin 3 mA of the amplifiers. Exceeding a temperature of 150°C for an Human Body Model (HBM) ESD Rating ±4000 V extended period can result in a loss of functionality. Storage Temperature Range −65°C to +130°C The AD8273 has built-in, short-circuit protection that limits the Specified Temperature Range −40°C to +85°C output current to approximately 100 mA (see Figure 2 for more Thermal Resistance information). While the short-circuit condition itself does not θJA 105°C/W damage the part, the heat generated by the condition can cause θJC 36°C/W the part to exceed its maximum junction temperature, with Package Glass Transition Temperature (TG) 150°C corresponding negative effects on reliability. Stresses above those listed under Absolute Maximum Ratings 2.0TJ MAX = 150°C may cause permanent damage to the device. This is a stress θJA = 105°C/W) rating only; functional operation of the device at these or any (W1.6N other conditions above those indicated in the operational IO T section of this specification is not implied. Exposure to absolute IPA S1.2 maximum rating conditions for extended periods may affect IS D device reliability.
