Notes for use
1) The above numerical values and data are typical values for the design, which are not guaranteed.
2) The application circuit examples can be reliably recommended, but their characteristics should be checked carefully
before use. When using external component constants that have been modified, determine an ample margin that takes
into consideration variation among the external components and Rohm's LSI IC chips, including variation in static
characteristics and transient characteristics.
3) Absolute maximum ratings
This IC may be damaged if the absolute maximum ratings for the applied voltage, temperature range, or other parameters
are exceeded. Therefore, avoid using a voltage or temperature that exceeds the absolute maximum ratings. If it is possible
that absolute maximum ratings will be exceeded, use fuses or other physical safety measures and determine ways to
avoid exceeding the IC's absolute maximum ratings. The above numerical values and data are typical values for the
design, which are not guaranteed.
4) GND pin's potential
Try to set the minimum voltage for GND pin's potential, regardless of the operation mode.
Check that the voltage of each pin does not go below GND pin's voltage, including transient phenomena.
5) Shorting between pins and mounting errors
When mounting the IC chip on a board, be very careful to set the chip's orientation and position precisely. When the power
is turned on, the IC may be damaged if it is not mounted correctly. The IC may also be damaged if a short occurs (due to
a foreign object, etc.) between two pins, between a pin and the power supply, or between a pin and the GND.
6) Shorting output pin
When output pin (5,8pin) is shorted to VCC or GND, the IC may be damaged by over current, so be careful in operation.
7) Thermal design
Ensure sufficient margins to the thermal design by taking in to account the allowable power dissipation during actual use
modes, because this IC is power amp.
When excessive signal inputs which the heat dissipation is insufficient condition, it is possible that TSD (thermal shutdown
circuit) is active.
TSD is protection of the heat by excessive signal inputs, it is not protection of the shorting output to VCC or GND.
8) Shorted pins and mounting errors
When the output pins (pins 5 and 8) are connected to VCC and GND, the thermal shutdown function repeatedly switches
between shutdown (OFF) and cancel (ON). Note with caution that chip damage may occur if these connections remain
for a long time.
9) Operating range
The rated operating power supply voltage range(VCC=+2.4 +5.5V) and the rated operation temperature range
(Ta=-40+85) are the range by which basic circuit functions is operated.
It is not guaranteed a specification and a rated output power about all operating power supply voltage range or operation
temperature range.
10) Operation in strong magnetic fields
Note with caution that operation faults may occur when this IC operates in a strong magnetic field.
