• (1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If used outside the Section 5.3 but within the Absolute Maximum Ratings , the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.
• (2) All voltage values, except differential voltages, are with respect to the midpoint between V CC+ and V CC-.
• (3) The magnitude of the input voltage must never exceed the magnitude of the supply voltage.
• (4) Excessive input current flows if a differential input voltage in exceeding approximately 0.6V is applied between the inputs, unless some limiting resistance is used.
• (5) The output can be shorted to ground or either power supply. Temperature and/or supply voltages must be limited to the maximum dissipation rating is not exceeded.

• (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report .

(2) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) - TA) / θ JA. Operating at the absolute maximum T J of 150°C can affect reliability.

• (3) The package thermal impedance is calculated in accordance with JESD 51-7.

Some applications require differential signals. Figure 7-1 shows a simple circuit to convert a single-ended input of 2V to 10V into differential output of ±8V on a single 15V supply. The output range is intentionally limited to maximize linearity. The circuit is composed of two amplifiers. One amplifier acts as a buffer and creates a voltage, VOUT+. The second amplifier inverts the input and adds a reference voltage to generate VOUT-. Both VOUT+ and VOUT- range from 2V to 10V. The difference, VDIFF, is the difference between VOUT+ and VOUT-.
