INA 163 it's a BURR-BROWN product isn't it ?
It cost twice than the best taiwanese 150W car amplifier...[final product,
in aluminium case, 1V input]
I have doubts it will be cheap, but maybe I'm wrong, you have some
discounts there ?
I've buy an OPA128 a while ago, with that money I sould buy two kilograms
of other operational amplifiers...
