Note 1:
Stresses beyond those listed under Absolute Maximum Ratings meet specifi ed performance from –40°C to 85°C but is not tested or may cause permanent damage to the device. Exposure to any Absolute QA sampled at these temperatures. The LTC6702I is guaranteed to meet Maximum Rating condition for extended periods may affect device specifi ed performance from –40°C to 85°C. The LTC6702H is guaranteed reliability and lifetime. to meet specifi ed performance from –40°C to 125°C.
Note 2:
A heat sink may be required to keep the junction temperature
Note 5:
The LTC6702 comparators include internal hysteresis. The offset below absolute maximum. This depends on the power supply voltage and voltage is defi ned as the average of the input voltages (trip points) how many comparators are shorted. The θJA specifi ed for the DC and required to change the output in each direction minus VCM, while the TS packages is with minimal PCB heat spreading metal. Using expanded hysteresis voltage is the difference of these trip points. metal area on all layers of a board reduces this value.
Note 6:
Output voltage swings are measured between the output and
Note 3:
The LTC6702C and LTC6702I are guaranteed functional over power supply rails. the temperature range of –40°C to 85°C. The LTC6702H is guaranteed
Note 7:
Propagation delay is for 200mV steps, and 50mV of overdrive. functional over the operating temperature range of –40°C to 125°C. Overdrive is measured relative to the positive and negative trip points.
Note 4:
The LTC6702C is guaranteed to meet specifi ed performance from 0°C to 70°C. The LTC6702C is designed, characterized and expected to 6702fa 3
