The TPA2008D2 is a third-generation, 5-V Class-D audio power amplifier from Texas Instruments, designed for stereo applications. It delivers 3 W per channel into 3-Ω speakers with a typical THD+N of 0.3% at 1 kHz. A key feature is its filter-free modulation scheme, which eliminates the need for a large LC output filter, saving system cost and PCB area.
This amplifier operates with analog supply voltages ranging from 2.5 V to 5.5 V and a power stage supply from 4.5 V to 5.5 V. It includes DC volume control with 2-dB steps from -38 dB to 20 dB. The device boasts high efficiency, reaching up to 78% into a 3-Ω load and 88% into an 8-Ω load. It also features low supply current (7 mA typical) and a low shutdown current (1 µA typical), making it suitable for battery-powered devices.
The TPA2008D2 operates within a temperature range of -40°C to 85°C. It is available in a space-saving, surface-mount HTSSOP (PWP) package measuring 7.8 mm × 6.4 mm with an area of 49.92 mm². Integrated depop circuitry enhances reliability.
Applications for the TPA2008D2 include LCD projectors, LCD monitors, powered speakers, and other battery-operated systems where space and power efficiency are critical.
