The TPA2011D1 from Texas Instruments is a high-efficiency, filter-free Class-D audio power amplifier designed for portable applications. This device delivers up to 3.24W into a 4 ℆ load with 10% THDN, or 2.57W with 1% THDN. It operates from a power stage supply voltage range of 2.5V to 5.5V and an analog supply voltage of 2.5V to 5.5V.
Key features include 95% efficiency, a low quiescent current of 1.5 mA, and auto-recovering short-circuit protection. The amplifier also incorporates an integrated feedback resistor of 300 k℆ and an integrated image reject filter for DAC noise reduction. Its low output noise of 20 µV and fast 4 ms start-up time make it suitable for demanding audio applications.
The TPA2011D1 is available in a compact 9-ball, 1.21mm x 1.16mm DSBGA package, requiring minimal external components. This makes it ideal for space-constrained designs in wireless handsets, PDAs, portable navigation devices, and general portable audio equipment.
This amplifier is designed for analog input and features hardware control. Its operating temperature range is -40°C to 85°C.
