AUDIO/ILM output voltage setting method
Formula for AUDIO voltage calculation
The circuit must be designed in such a way that the R1:R2 ratio
satisfies the formula given above for the AUDIO voltage that
has been set.
Example : AUDIO = 8.5V setting method
The AUDIO_F voltage is determined by the
internal band gap voltage of the IC (typ = 1.26V).
The ILM output voltage can be set by the above-mentioned method.
Note : In the above, the typical values are given in all instances for the values used and, as such, they will vary due to the
effects of production-related variations of the IC and external resistors.
