Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 2:
The LTC1258 is guaranteed functional over the operating may cause permanent damage to the device. Exposure to any Absolute temperature range of –40°C to 100°C. Maximum Rating condition for extended periods may affect device
Note 3:
If the part is stored outside of the specifi ed operating temperature reliability and lifetime. range, the output may shift due to hysteresis. 1258sfb 3
