TPA2008D2PWPR

TEXAS INSTRUMENTS  TPA2008D2PWPR  音频功率放大器, HTSSOP

The is a 3W stereo Class D Audio Amplifier with volume control and fewer external components. Most notably, a new filter-free class-D modulation technique allows the TPA2008D2 to directly drive the speakers, without needing a low-pass output filter consisting of two inductors and three capacitors per channel. Eliminating this output filter saves approximately 30% in system cost and 75% in PCB area. The improvements and functionality make this device ideal for LCD projectors, LCD monitors, powered speakers and other applications that demand more battery life, reduced board space and functionality that surpasses currently available class-D devices. A chip-level shutdown control limits total supply current to 1µA, making the device ideal for battery-powered applications. Protection circuitry increases device reliability: thermal and short circuit. Undervoltage shutdown saves battery power for more essential devices when battery voltage drops to low levels.
