description
The TPA032D04 is a monolithic power IC stereo
audio amplifier that operates in extremely efficient
Class-D operation, using the high switching speed
of power DMOS transistors to replicate the analog
input signal through high-frequency switching of
the output stage. This allows the TPA032D04 to
be configured as a bridge-tied load (BTL) amplifier
capable of delivering up to 10 W of continuous
average power into a 4-
load at 0.5% THD+N
from a 12-V power supply in the high-fidelity audio
frequency range (20 Hz to 20 kHz). A BTL
configuration eliminates the need for external
coupling capacitors on the output. Included is a Class-AB headphone amplifier with interface logic to select
between the two modes of operation. Only one amplifier is active at any given time, and the other is in
power-saving sleep mode. Also, a chip-level shutdown control is provided to limit total supply current to 20
μ
A,
making the device ideal for battery-powered applications.
The output stage is compatible with a range of power supplies from 8 V to 14 V. Protection circuitry is included
to increase device reliability: thermal and under-voltage shutdown, with a status feedback terminal for use when
any error condition is encountered.
The high switching frequency of the TPA032D04 allows the output filter to consist of three small capacitors and
two small inductors per channel. The high switching frequency also allows for good THD+N performance.
The TPA032D04 is offered in the thermally enhanced 48-pin PowerPAD TSSOP surface-mount package
(designator DCA).
