General Description
The FPA6101 is a monolithic integrated circuit combin-
ing a stereo power amplifier with a stereo capacitor-less
headphone amplifier in a space and cost efficient
package. The headphone amplifier is ground-referenced
to eliminate the output capacitors saving money and
PCB space.
The amplifier features over-current, de-pop and thermal-
shutdown protection. De-Pop reduces pops and clicks
during power up and when using the shutdown modes.
Thermal shut-down protects the amplifier from being
destroyed by over-temperature or short-circuit failure.
Internal gain setting is provided to simplify the audio
system design in notebook computer applications and
can result in fewer support components and a reduction
in PCB area. The FPA6101 is available in a TSSOP-28P
or MLP-28P package. Both packages provide space
saving and thermal efficiency.

Note:
FAIRCHILD lead-free products contain molding compounds/die attach
materials and 100% matte tin plate termination finish; which are fully compliant
with RoHS and compatible with both SnPb and lead-free soldiering operations.
FAIRCHILD lead-free products meet or exceed the lead-free requirements of
IPC/JEDEC J STD-020C for MSL classification at lead-free peak reflow temperature.
