ADS8681: Max Junction Temperature

Hi Jejomar,

An estimation of the chip-junction temperature, T_J,  can be obtained from the following equation:

T_J = T_A + ( R _θJA × P_D ) = 25˚C + (95.7˚C/W*65mW) = 31.22°C

where:

T_A = ambient temperature for the package ( °C )  – 25°C as an example

R_θJA = junction to ambient thermal resistance ( °C / W )  – 95.7°C/W for TSSOP package, 31.9°C/W for WQFN package

P_D = power dissipation in package (W)  – 65mW for ADS8681

Thanks&regards,

Dale
