NOTE 1: ABSOLUTE MAXIMUM RATINGS ARE THOSE BEYOND WHICH THE LIFE OF A
DEVICE MAY BE IMPAIRED.
NOTE 2 : THE LTC3204-3.3/LTC3204-5/LTC3204B-3.3/LTC3204B-5 ARE
GUARANTEED TO MEET PERFORMANCE SPECI?CATIONS FROM 0°C TO 70°C.
SPECI?CATIONS OVER THE –40°C TO 85°C OPERATING TEMPERATURE RANGE ARE
ASSURED BY DESIGN, CHARACTERIZATION AND CORRELATION WITH STATISTICAL PROCESS
CONTROLS.
