Typical values are measured of about 5000 devices of Lot 4234011, Week Code 0452.
1 3.0 volts can be achieved with +-to-+ wiring for mono difference sound.
2 AOLR may be much lower, but below Typical distortion performance may be compromised.
3 Above typical amplitude the Harmonic Distortion increases.
4 Unweighted, A-weighted is about 3 dB better.
5 Limit low due to noise level of production tester.
