The TI OPA2209D is pin for pin compatible. It's the same package, and it specifies a maximum supply current of 2.5mA; whereas the AD8599 has a typical supply current spec of 4.8mA.
I'm getting samples to try out. Going just by that specification, the power could be cut in half.
There are no measurable oscillations in the input or output signals. That was one of the first things that we looked for.
I'm wondering if we meet the assumed criteria for ground plane size, thermal vias and such that the data sheet specifies.
There are many times that I've read a data sheet...
We've measured temperatures of 90C-100C on the case at room temperature. The part itself can withstand a 150C junction temperature, but there are two of these op-amps heating up our entire board. Other devices aren't running optimally with all of the heat around.
We need to run the op-amp...
