† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. § Thermal shutdown activates when TJ = 125°C. NOTE 1: Pulse duration = 10 ms, duty cycle 2%
DescriptionThe 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 replica te the analog signal through high-frequency 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 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 A. 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).
