AC CHARACTERISTICS (V
T
(maximum gain = 20 dB); according to Fig.4; package is SO20.
Notes
1. Volume setting at maximum.
2. The noise output voltage is measured at the output in a frequency band from 20 Hz to 20 kHz (unweighted),
3. Supply voltage ripple rejection is measured at the output, with a source impedance of R
4. Channel suppression is measured at the output with a source impedance of R
