• Wide Power Supply Range: 1.8 V to 4.5 V

• 80-mW/Ch Output Power into 16-Ω at 4.5 V

• Independent Right and Left Channel

Shutdown Control

• Short-Circuit and Thermal Protection

The TPA4411 and TPA4411M are stereo headphone

• Pop Reduction Circuitry

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

• Notebook Computers

critical design parameters.

• CD / MP3 Players

The TPA4411 and TPA4411M are capable of driving

• Smart Phones

80 mW into a 16-

Ω load at 4.5 V. Both TPA4411 and

• Cellular Phones

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

• PDAs

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.
