The TPA3007D1 from Texas Instruments is a 6.5-watt mono Class-D audio power amplifier designed for high efficiency without requiring a heat sink. It features an analog input and can drive 8-ohm speakers.
This amplifier operates with a power stage supply voltage ranging from 8V to 18V, and an analog supply voltage also between 8V and 18V. It achieves a low total harmonic distortion plus noise (THD+N) of 0.19% at 1 kHz. The device is suitable for loads as low as 7 ohms.
The TPA3007D1 utilizes a third-generation modulation technique, allowing for a small, low-cost ferrite bead filter in most applications, reducing EMI. It includes features like high common mode rejection, improved power supply rejection, and "de-pop" circuitry to minimize noise during power-up and shutdown transitions.
Applications for the TPA3007D1 include LCD monitors and TVs, desktop replacement systems, notebook PCs, hands-free car kits, and powered speakers. The amplifier is available in a 24-pin TSSOP package.
