Hi!
NOTE!: I don't understand why I HAVE to type a part number. This question is NOT about a particular TI product!
I need to "play" a broadband audio white noise signal into 2 "speakers", in the form of 2 telephone pick-up coils with R=280 Ohm and L=159 mH, to create 2 equal 'excitation fields' for a scientific measurement purpose, where 2 other coils will pick up the response and an instrumentation amplifier will amplify the difference between the 2 signals. So the most important criteria for the amplifier driving the 2 "speaker" coils is that the difference between the output to the 2 "speakers" is as small as possible... Which audio stereo amplifier is best suited for this?
I am sorry that my question is so unusual... ;-) :-)
