20 W Into 8-
Load From 18-V Supply (10%
The
TPA3001D1
(sometimes
referred
to
as
THD+N)
TPA3001) is a 20-W monaural bridge-tied load (BTL)
class-D audio power amplifier (class-D amp) with high
Short-Circuit Protection (Short to VCC, Short to
efficiency, eliminating the need for heat sinks. The
GND, Short Between Outputs)
TPA3001D1 can drive 4-
or 8- speakers with only
Third-Generation Modulation Technique:
a ferrite bead filter required to reduce EMI.
–
Replaces Large LC Filter With Small,
The gain of the amplifier is controlled by two input
Low-Cost Ferrite Bead Filter in Most
terminals,
GAIN1
and
GAIN0.
This
allows
the
Applications
amplifier to be configured for a gain of 12, 18, 23.6,
–
Improved Efficiency
or 36 dB. The differential input stage provides high
common-mode rejection and improved power-supply
–
Improved SNR
rejection.
Low Supply Current: 8 mA Typ at 12 V
The amplifier also includes depop circuitry to reduce
Shutdown Control: < 1 mA Typ
the amount of pop at power-up and when cycling
Space-Saving, Thermally-Enhanced
SHUTDOWN.
PowerPAD Packaging
The TPA3001D1 (TPA3001) is available in the 24-pin
thermally enhanced TSSOP package (PWP), which
APPLICATIONS
eliminates the need for an external heat sink.
