Supply Voltage 20V Input Voltage Range, V pk V S/2 Operating Temperature (Note 2) 0˚C to +70˚C Storage Temperature −65˚C to +150˚C Soldering Information Dual-In-Line Package Soldering (10 seconds) 260˚C Small Outline Package Vapor Phase (60 seconds) 215˚C Infrared (15 seconds) 220˚C See AN-450 “Surface Mounting Methods and Their Effect on Product Reliability” for other methods of soldering surface mount devices. Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits.
