3 Description
The TPA3140D2 is an efficient, Class-D audio power
amplifier for driving bridged-tied stereo speakers at
up to 10 W, 6 , or 8 (per channel).
Advanced EMI Suppression Technology with Spread
Spectrum Control and 1SPW modulation scheme
enables the use of inexpensive ferrite bead filters at
the outputs while meeting EMC requirements for
system cost reduction. TPA3140D2 is not only fully
protected against shorts and overload, the
SpeakerGuard™ speaker protection circuitry includes
an adjustable Automatic Gain Limit (AGL), an
adjustable power limiter and a DC detection circuit for
protection of the connected speakers. The AGL
allows adjustment of the maximum output voltage
without signal clipping for enhanced speaker
protection and audio quality. The DC detect and Pin-
to-Pin, Pin-to-Ground, and Pin-to-Power Short Circuit
protection circuit protect the speakers from output DC
and pin shorts caused in production. The outputs are
also fully protected against shorts to GND, PVCC,
and output-to-output. The short-circuit protection and
thermal protection includes an auto recovery feature.
The TPA3140D2 can drive stereo speakers with as
low as 4-Ω impedance. The high efficiency of the
TPA3140D2, 90% with an 8-load, eliminates the
need for an external heat sink, and TPA3140D2 will
be able to output full power on a 2-layer PCB.
