DESCRIPTION
The LM4875 is a mono bridged audio power amplifier
with DC voltage volume control. The LM4875 is
capable of delivering 750mW of continuous average
power into an 8load with less than 1% THD when
powered by a 5V power supply. Switching between
bridged speaker mode and headphone (single ended)
mode is accomplished using the headphone sense
pin. To conserve power in portable applications, the
LM4875's micropower shutdown mode (IQ = 0.7µA,
typ) is activated when less than 300mV is applied to
the DC Vol/SD pin.
Boomer audio power amplifiers are designed
specifically to provide high power audio output while
maintaining high fidelity. They require few external
components and operate on low supply voltages.

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.

(1) 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 that ensure specific performance limits. This assumes that the device operates within the
Operating Ratings. Specifications are not ensured for parameters where no limit is given. The typical value, however, is a good
indication of device performance.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature
TA. The maximum allowable power dissipation is PDMAX = (TJMAX TA)/θJA or the number given in the Absolute Maximum Ratings,
whichever is lower. For the LM4875M, TJMAX = 150°C.
(4) Human body model, 100pF discharged through a 1.5kresistor.
(5) Machine Model, 220pF–240pF discharged through all pins.
