operation sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of
time may affect reliability.
PACKAGE THERMAL CHARACTERISTICS (Note 1)
PDIP
Junction-to-Ambient Thermal Resistance (θJA).…………………...……………………....110°C/W
Junction-to-Case Thermal Resistance (θJC)…………………………………………………40°C/W
SO
Junction-to-Ambient Thermal Resistance (θJA).…………………………………………...136°C/W
Junction-to-Case Thermal Resistance (θJC)…………………………………………………38°C/W
Note 1:
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board for the SO. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial.
