The Texas Instruments TPA3003D2PFB is an efficient, 3-W per channel Class-D audio amplifier designed for driving bridged-tied stereo speakers. It supports speaker loads as low as 8 ohms and operates with an analog supply voltage between 2.7V and 5V, and a power stage supply up to 14V.
This amplifier features a 32-step DC volume control, offering a gain range from -40 dB to 36 dB. Its Class-D operation eliminates the need for external heatsinks when playing music, reducing power supply requirements and board space. The TPA3003D2PFB is suitable for applications such as LCD monitors and TVs, and powered speakers.
The device comes in a TQFP (PFB) package with dimensions of 9 mm x 9 mm, covering an area of 81 mm². It operates within a temperature range of -40°C to 85°C. The amplifier utilizes third-generation modulation techniques and replaces large LC filters with a small, low-cost ferrite bead filter. It also includes thermal and short-circuit protection.
The TPA3003D2PFB provides 3 W per channel into an 8-ohm load from a 12-V supply.
The analog supply voltage range is from 2.7 V to 5 V.
The minimum load impedance is 8 Ω.
The TPA3003D2PFB uses analog input.
The operating temperature range is -40°C to 85°C.
