Note 2: The inputs are protected by back-to-back diodes. If the differential Note 8: This parameter is not 100% tested. input voltage exceeds 1.4V, the input current should be limited to less than Note 9: Thermal resistance varies depending upon the amount of PC board 10mA. metal attached to the V– pin of the device. θJA is specifi ed for a certain Note 3: A heat sink may be required to keep the junction temperature amount of 2oz of copper metal trace connecting to the V– pin as described below the absolute maximum rating when the output is shorted in the thermal resistance tables in the Applications Information section. indefi nitely.

Note 5: The LT1809C/LT1810C are guaranteed to meet specifi ed performance from 0°C to 70°C. The LT1809C/LT1810C are designed, characterized and expected to meet specifi ed performance from –40°C to 85°C but are not tested or QA sampled at these temperatures. The LT1809I/LT1810I are guaranteed to meet specifi ed performance from –40°C to 85°C. 180910fa 10
