description
The TPA005D12 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 TPA005D12 to

frequency range (20 Hz to 20 kHz). A BTL configuration eliminates the need for external coupling capacitors
on the output. A chip-level shutdown control is provided to limit total quiescent current to 0.2 µA, making the
device ideal for battery-powered applications.
A full range of protection circuitry is included to increase device reliability: thermal, over-current, and
under-voltage shutdown, with two status feedback terminals for use when any error condition is encountered.
The high switching frequency of the TPA005D12 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 TPA005D12 is offered in the thermally enhanced 48-pin PowerPAD TSSOP surface-mount package
(designator DCA).
