The document describes the features and characteristics of the product in SLOS429 - MAY 2004. The product is designed for wireless or cellular handsets and PDAs. It has features such as low supply current, fast startup, and small PCB area, making it ideal for applications such as wireless handsets, PDAs, and notebook computers.
The TPA6204A1 is a fully‑differential audio power amplifier designed for wireless handsets, PDAs and notebook computers. It operates from 2.5 V to 5.5 V, delivers up to 1.7 W into an 8 Ω load, and draws only 4 mA quiescent current.
The device is offered in a compact 3 mm × 3 mm QFN (DRB) package and includes features such as –80 dB PSRR, –63 dB CMRR, fast startup with minimal pop, and shutdown current of 0.01 µA. Typical application schematics and component‑selection guidelines are provided.
