Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Inputs are protected by back-to-back diodes. If the differential
input voltage exceeds 0.7V, the input current must be limited to less than
40mA.
Note 3: A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output is shorted
indefinitely.
Note 4: The LT6230C/LT6230I the LT6231C/LT6231I, and LT6232C/LT6232I
are guaranteed functional over the temperature range of –40°C and 85°C.
Note 5: The LT6230C/LT6231C/LT6232C are guaranteed to meet specified
performance from 0°C to 70°C. The LT6230C/LT6231C/LT6232C are
designed, characterized and expected to meet specified performance from
–40°C to 85°C, but are not tested or QA sampled at these temperatures.
The LT6230I/LT6231I/LT6232I are guaranteed to meet specified
performance from –40°C to 85°C.
