The TPA005D02 is a monolithic power IC stereo

audio amplifier. It operates in extremely efficient

Class-Doperation, usingthehighswitchingspeed

of power DMOS transistors. These transistors

replicate the analog signal through high-frequen-

cy switching of the output stage. This allows the

TPA005D02 to be configured as a bridge-tied load

(BTL) amplifier.

When configured as a BTL amplifier, the

TPA005D02 is capable of delivering up to 2 W of

continuous average power into a 4-Ω load at 0.5%

THD+Nfroma5-Vpowersupplyinthehighfidelity

range (20 Hz to 20 kHz).

A BTL configuration eliminates the need for external coupling capacitors on the output. A chip-level shutdown

control limits total supply current to 400 µA. This makes the device ideal for battery-powered applications.

Protection circuitry increases device reliability: thermal and under-voltage shutdown, with two status feedback

terminals for use when any error condition is encountered.

The high switching frequency of the TPA005D02 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 TPA005D02 is offered in the thermally enhanced 48-pin PowerPAD TSSOP surface-mount package

(designator DCA).
