[sdiy] low supply voltage dual opamp ???

[Jean-Pierre Desrochers]

I need a low voltage dual opamp for a wireless microphone
That runs with  one  AAA battery. There is a step-up supply voltage circuit
that
rise the 1.5v to 5vdc to supply all the remote circuit including
a dual opamp (single supply used). This opamp needs to be changed.
All I can say about this opamp is that the case is a 8SOIC and the pinout
is the same as a TL072. The lettering on the case is :
690 followed by 055 (or D55 ???).
So I'm looking for a low supply voltage, low power and quiet dual opamp to
replace it.
Any idea ?
Thamks.
