The minimum value of the headroom margin is specified as 12 dB by Dolby Laboratories. HA12155 series
are provided with two line output level, which will permit an optimum headroom margin for power supply
conditions.
Reference Voltage
For the single supply operation these devices provide the reference voltage of half the supply voltage that is
the signal grounds. As the peculiarity of these devices, the capacitor for the ripple filter is very small about
1/100 compared with their usual value. The Reference voltage are provided for the left channel and the
right channel separately. The block diagram is shown as figure 1.

Operating Mode Control
HA12155NT/HA12157NT provides fully electronic switching circuits. NR-ON/OFF, C/B, and MPX
ON/OFF switches are controlled by parallel data (DC voltage) and other switches are controlled by serial
data.
