Product data sheet Rev. 2 — 11 August 2010 5 of 10 NXP Semiconductors TDA18272HN Hybrid Silicon Tuner for terrestrial and cable TV reception 6. Limiting values [1] The maximum allowed ambient temperature Tamb(max) depends on the assembly conditions of the package and especially on the design of the Printed-Circuit Board (PCB) and die connection. The application mounting must be done in such a way that the maximum junction temperature is never exceeded. The junction temperature can be obtained by reading the temperature sensor bit via I2C-bus. The junction temperature: Tj = Tamb + ΔTj-c. where ΔTj-c = power × Rth. [2] Class III: 500 V to 1000 V. 7.
