TPA2026D2 is a stereo, filter-free Class-D audio power amplifier with volume control, dynamic range compression (DRC), and automatic gain control (AGC) functions. It is suitable for power supply range from 2.5V to 5.5V, with output power of 3.2W/Ch (4Ω, 5V) and 750mW/Ch (8Ω, 3.6V). The DRC/AGC parameters, including gain range, attack/release/hold times, compression ratio, etc., can be programmed and configured via a digital I2C interface.
The TPA2026D2 is a stereo, filter‑free Class‑D audio power amplifier with integrated volume control, dynamic range compression (DRC) and automatic gain control (AGC). It is offered in a compact 2.2 mm × 2.2 mm Nano‑Free WCSP package and is targeted at portable applications such as handsets, PDAs, USB speakers and other battery‑powered devices.
The datasheet provides full pin‑out information, electrical specifications (supply range, output power, current consumption, PSRR, gain settings), timing diagrams for the I²C interface, mechanical drawings, and recommended operating conditions. It also lists safety notices and warranty information.
