Note 1:
Stresses beyond those listed under Absolute Maximum Ratings characterization and correlation with statistical process controls. The may cause permanent damage to the device. Exposure to any Absolute junction temperature (TJ in °C) is calculated from the ambient temperature Maximum Rating condition for extended periods may affect device (TA, in °C) and power dissipation (PD, in watts) according to the formula: reliability and lifetime. TJ = TA + (PD • θJA),
Note 2:
All currents into pins are positive; all voltages are referenced to where the package thermal impedance θJA = 92°C/W). GND unless otherwise noted. Note that the maximum ambient temperature consistent with these
Note 3:
The LTC4126-10E is tested under conditions such that T specifications is determined by specific operating conditions in J ≈ TA. The LTC4126-10E is guaranteed to meet performance specifications conjunction with board layout, the rated package thermal resistance, and from 0°C to 85°C junction temperature. Specifications over the –20°C other environmental factors. to 85°C operating junction temperature range are assured by design,
