Note 1:
Stresses beyond those listed under Absolute Maximum Ratings these specifications is determined by specific operating conditions in may cause permanent damage to the device. Exposure to any Absolute conjunction with board layout, the rated package thermal impedance Maximum Rating condition for extended periods may affect device and other environmental factors. The junction temperature (TJ, in °C) is reliability and lifetime. calculated from the ambient temperature (TA, in °C) and power dissipation
Note 2:
The LTC4000-1 is tested under conditions such that T (P J ≈ TA. D, in Watts) according to the following formula: The LTC4000E-1 is guaranteed to meet specifications from 0°C to 85°C TJ = TA + (PD • θJA), where θJA (in °C/W) is the package thermal junction temperature. Specifications over the –40°C to 125°C operating impedance. junction temperature range are assured by design, characterization
Note 3:
All currents into pins are positive; all voltages are referenced to and correlation with statistical process controls. The LTC4000I-1 is GND unless otherwise noted. guaranteed over the full –40°C to 125°C operating junction temperature
Note 4:
These parameters are guaranteed by design and are not 100% range.
