DESCRIPTION

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.

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.
