Application Notes
1. Mute switch and voltage gain
This IC is designed to ensure there is no perceptible change in volume whether a single output or several
outputs are used.
When the input signal to the three buffer amplifiers is the same and in a linear domain, the relation
between the mute switches and voltage gain is as follows:
Test condition: V
CC
=
3 V, f
=
1 kHz, V
in
=
20 dBV, theoretical value.
