Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to Absolute Maximum Ratings.

Notes:
1.
Capacitors experience degradation over time and this is accelerated with increased temperature. It is therefore
recommended to use the stated typical values.
2.
The FAB3103 is optimized to drive an 8 speaker impedance. The 8 speaker should remain at ≥6 over the
entire audio frequency range.
