MAXIMUM RATINGS (Tamb=25°C) Symbol Parameter Value Unit VCC Supply Voltage ±18 V DIP8 500 SIP8 800 Pd Power Consumption SOP8 300 mw VID Differential Input Voltage ±15 V VI Common-Mode Input Voltage ±15 V Tamb Operating Free-air Temperature Range 0 to +70 °C Tstg Storage Temperature Range -25 to +125 °C * Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the Recommended Operating Conditions. RECOMMENDED OPERATING CONDITIONS Symbol Parameter Min Max Unit V+ Supply Voltage +15 V V- Supply Voltage -15 V TA Operating Temperature, All Pakage Types 0 +70 °C This device contains protection circuitry to guard ag ainst damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of an y voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, V IN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V CC). Unused outputs must be left open.
