The TPA3128D2DAP from Texas Instruments is an analog input Class-D audio amplifier designed for home audio applications. It delivers 30W of stereo output power into an 8Ω load at 24V, or 60W in mono mode. The device operates over a wide supply voltage range from 4.5V to 26V, providing flexibility for various power designs.
Key features include high power efficiency exceeding 90% and very low idle current consumption of less than 23mA, which helps reduce heat dissipation and power waste. The amplifier incorporates integrated self-protection circuits for overvoltage, undervoltage, overtemperature, DC-detect, and short circuits, enhancing reliability. It supports multiple output configurations and offers adaptive modulation schemes for optimized performance.
The TPA3128D2DAP is available in a 32-pin HTSSOP (DAP) thermally enhanced package, measuring 11 mm x 8.1 mm with an area of 89.1 mm². This package is designed for efficient heat dissipation, potentially eliminating the need for a heatsink in some applications. The control interface is hardware-based, and the input type is analog.
