? ILM output voltage setting method
Formula for ILM voltage calculation
Z 1 = R 2 // R 3 =
R 2 ? R 3
R 2 + R 3

ILM
ILM =
1.26[ V ]
R 1
× Z 1 + 1 . 26 [ V ]
R2 59.67k Ω

ILM_F
R3
Z1=R2/R3
Z 1 =
( ILM ? 1.26 ) ? R 1
1.26
R 3 =
R 2 ? Z 1
R 2 ? Z 1
R1 7k Ω
Example : ILM = 9V setting method
( 9 V ? 1.26 V ) ? 7 k ? ? 43 k ?
Z 1 =
1.26 V
The ILM_F voltage is determined by the
internal band gap voltage of the IC (typ = 1.26V).
When R3 = 150k, the ILM output voltage will be as follows:
Z 1 ′ =
59.67 k ? ? 150 k ?
59.67 k ? + 150 k ?
? 42.69 k ?
ILM =
1.26 V
7 k ?
× 42.69 k ? + 1.26 V ? 8.94 V
? AUDIO output voltage setting method
Formula for AUDIO voltage calculation
AUDIO =
1.26[ V ]
R 2
× R 1 + 1.26[ V ]

R 2
=

AUDIO_F
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.
R2
Example : AUDIO = 8.5V setting method
( 8.5 ? 1.26 ) ? 5.75
The AUDIO_F voltage is determined by the
R 1
R 2
=
1.26
internal band gap voltage of the IC (typ = 1.26V).
R 1
R 2
=

4.7 k ?
? 5.74
AUDIO = 1.26 V × 5.74 + 1.26 V ? 8.49 V
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.
