Junction to Case (Note 2)

θJC

°C/W

Notes: 1. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air.

The exposed pad of HSOP-8 is soldered directly on the PCB.

2. The Thermal Pad Temperature is measured on the PCB copper area connected to the thermal pad of

package.
