GENERAL DESCRIPTION
Low cost is assured by trimming and calibration at the wafer level. It can be used with a single power supply, or with plus and minus supplies. As it draws only 120 µA from its supply, it has very low self-heating, less than 0.2˚C in still air. The LM45 is rated to operate over a −20˚ to +100˚C temperature range. n n n n n n Portable Medical Instruments HVAC Power Supply Modules Disk Drives Computers Automotive FEATURES
