# Maximum Junction Temperature of ADM3491

Maximum Junction Temperature of ADM3491 is not available in datasheet. Please provide the same

• Hi Veerasamy,

The junction temperature for the part can be calculated if we know what the power dissipation is:

Tj = TA + θja*Pdiss

The 14-ld N-SOIC ADM3491 has a θJA Thermal Impedance of 86°C/W (for a 4layer board).
