Functional Description
Power Supply Range
HA12192F series and HA12197F series are provided with three line output level, which will permit on
optimum overload margin for power supply conditions. And these series are designed to operate on single
supply only.

HA12194F, HA12199F
Note:
The lower limit of supply voltage depends on the line output reference level.
The minimum value of the overload margin is specified as 12dB by Dolby Laboratories.
7.2V to 15.0V
Reference Voltage
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 block diagram is shown as figure 1.
