Figure 5. Typical BTL Speaker Configuration Circuit
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not ensure specific performance limits. Electrical Characteristics state DC and AC electrical
specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the
Operating Ratings. Specifications are not ensured for parameters where no limit is given, however, the typical value is a good indication
of device performance.

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3)
The maximum power dissipation is dictated by TJMAX, θJA, and the ambient temperature TA and must be derated at elevated
temperatures. The maximum allowable power dissipation is PDMAX = (TJMAX − TA)/θJA. For the LM4916, TJMAX = 150°C. For the θJAs,
please see the APPLICATION INFORMATION section or the ABSOLUTE MAXIMUM RATINGS()() section.
(4)
Human body model, 100pF discharged through a 1.5k
Ω resistor.
(5)
Machine model, 220pF–240pF discharged through all pins.
OPERATING RATINGS
Temperature Range
TMIN ≤ TA ≤ TMAX
−40°C ≤ TA ≤ 85°C
Supply Voltage(1)
0.9V
≤ VDD ≤ 2.5V
(1)
When operating on a power supply voltage of 0.9V, the LM4916 willl not function below 0°C. At a power supply voltage of 1V or greater,
the LM4916 will operate down to -40°C.
