1 / 25 page TPA005D02 2-W STEREO CLASS-D AUDIO POWER AMPLIFIER SLOS227C – AUGUST 1998 – REVISED MARCH 2000 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 NOT RECOMMENDED FOR NEW DESIGNS D Choose TPA2000D2 For Upgrade D Extremely Efficient Class-D Stereo Operation D Drives L and R Channels D 2-W BTL Output into 4 Ω D 5-W Peak Music Power D Fully Specified for 5-V Operation D Low Quiescent Current D Shutdown Control D Thermally-Enhanced PowerPAD™ Surface- Mount Packaging D Thermal and Under-Voltage Protection description The TPA005D02 is a monolithic power IC stereo audio amplifier. It operates in extremely efficient Class-D operation, using the high switching speed 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+N from a 5-V power supply in the high fidelity 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).
