# 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).

For a thermal impedance of 86°C/W and a Max. ambient temperature of 85C the corresponding Junction temperature is 107C.

If you have concerns about operating at higher than +85C ambient, then the ADM3076E is an alternative part that can operate at up to +125C ambient.

Best Regards,

Richard
