Was denkst du über den OPA1694, der ist derzeit noch "PREVIEW" also nicht am Markt.

Zitat:The OPA169x family of amplifiers uses a propriety technology to reduce signal distortion that does not increase the power-supply current. The distortion cancellation technique reduces odd-order harmonic distortion, which is produced by the input transistor pair of the amplifier.
As Figure 8 illustrates, the impact to THD+N is significant, especially at high frequencies where the OPA169x devices exhibit over 30-dB lower distortion than competitor amplifiers at similar power-supply current levels.
