DESCRIPTION

•

Short-Circuit and Thermal Protection

Pop Reduction Circuitry

The TPA4411 and TPA4411M are stereo headphone

drivers designed to allow the removal of the output

DC-blocking capacitors for reduced component count

and cost. The TPA4411 and TPA4411M are ideal for

small portable electronics where size and cost are

critical design parameters.

APPLICATIONS

•

Notebook Computers

CD / MP3 Players

Smart Phones

Cellular Phones

PDAs

The TPA4411 and TPA4411M are capable of driving

80 mW into a 16-Ω load at 4.5 V. Both TPA4411 and

TPA4411M have a fixed gain of –1.5 V/V and

headphone outputs that have ±8-kV IEC ESD

protection. The TPA4411 and TPA4411M have

independent shutdown control for the right and left

audio channels.

The TPA4411 is available in a 2.18 mm × 2.18 mm

WCSP and 4 mm × 4 mm Thin QFN packages. The

TPA4411M is available in a 4 mm × 4 mm Thin QFN

package. The TPA4411RTJ package is a thermally

optimized PowerPAD™ package allowing the

maximum amount of thermal dissipation and the

TPA4411MRTJ is a thermally enhanced PowerPAD

package designed to match competitive package

footprints.
