(Note 19) Consider the power dissipation of the IC under high temperature environment when selecting the output current value.
There may be a case where the output current value is reduced due to the rise in IC temperature caused by the heat generated inside the IC.
(Note 20) Output load resistance connects to a half of VDD.

Datasheet
(16) Total Harmonic Distortion + Noise (THD+N)
Indicates the fluctuation of input offset voltage or that of output voltage with reference to the change of output voltage
of driven channel.
(17) Input Referred Noise Voltage (VN)
Indicates the noise voltage generated inside the operational amplifier equivalent to an ideal voltage source connected
in series with input terminal.
(18) Channel Separation (CS)
Indicates the fluctuation of the output voltage of the driven channel with reference to the change of output voltage of
the channel which is not driven.
