Very low current and low noise opamp

Vladimir Matveyev All Messages By This Member #36596 I'm wondering what are the most low current and low noise opamps for battery powered applications? Both fet input and bipolar. Recently I have been examining some electric violin preamp and noticed that it has tl062 inside. This one has very low power consumption but at the same time it is noisy as hell. Are there some modern low noise alternatives to this beast?

Jules Ryckebusch All Messages By This Member #36598 开云体育 The OPA1641 and 1642 are both low current with superb audio performance. ?There are lower current ones but at the expense of performance. These have 10X better noise performance than the TL062?
