    Here is the information you requested about LMH6525:

    1. Junction Temperature Max (Tj Max)                                         150C
    2. Typical Power, (Pd typ)                                                               Quiescent power with no load (Vs=5V)= 5V * 33mA= 165mW. Load related power will add to this!
    3. Maximum Power (Pd max)T                                                      Maximum power can be derived from 150C Tj Max, T_ambient, theta j-A and power dissipation
    4. Thermal Resistance Junction to Ambient (Theta JA)           30.8 deg. C/W as noted in the datasheet Note 10 (4 layer board, 9 thermal vias)
    5. Thermal Resistance Junction to Board (Theta JB)              ~20 deg. C/W (4 layer board, 9 thermal vias)
    6. Thermal Resistance Junction to Case (Theta JC)               ~10 deg. C/W (4 layer board, 9 thermal vias)
    7. Weight                                                                                           This information is not readily available but can be determined if need be?

    Thanks,

    Hooman
