TPA2028D1 Description

Short technical summary and product information.

The TPA2028D1 from Texas Instruments is a versatile mono Class-D audio amplifier designed for portable applications. It delivers up to 3 W into a 4 ℆ load at 5 V or 880 mW into an 8 ℆ load at 3.6 V, with a total harmonic distortion plus noise (THD+N) of 0.1% at 1 kHz.

This amplifier features a filter-free Class-D architecture and includes advanced functionalities such as SmartGain™, dynamic range compression (DRC), and automatic gain control (AGC). These features are programmable via a digital I2C interface, allowing for distortion prevention, enhancement of quiet passages, speaker protection, and dynamic range management. The gain is selectable from -28 dB to +30 dB in 1-dB steps.

Operating from a power supply range of 2.5 V to 5.5 V, the TPA2028D1 boasts a low supply current of 1.8 mA and a low shutdown current of 0.2 µA. It also offers high PSRR of 80 dB, short-circuit, and thermal protection. The device is available in a space-saving 1.63 mm x 1.63 mm wafer chip-scale package (DSBGA).

Ideal for wireless handsets, PDAs, portable navigation devices, notebook PCs, and USB speakers, the TPA2028D1 provides efficient audio amplification in a compact form factor.
