OPA132: Thermal metrics for OPA132

Part Number: OPA132
Other Parts Discussed in Thread: OPA827, OPA134

The OPA132 datasheet has no thermal resistance specs.   Do you think the thermal resistance specs for any old SOIC-8 op amp would be reasonably close?   Thanks...

    Hi Chris,

    I might be able to put you a little closer to some thermal numbers than those of just any old SOIC. I searched for another JFET input operational amplifier, having similar operating current to the OPA132. The OPA827 is similar in those regards, and I would expect their package thermal metrics to be similar as well.  

    See Sec. 6.4, on page 5, of the OPA827 datasheet for the thermal numbers:

    Hi Chris,

    I think we get even closer in terms of the OPA132 thermal metrics. We recently measured them for the OPA134 audio op amp and found its numbers. Please see the table shown below.
