Overview
The TPA2016D2RTJR is a stereo, filter-free Class-D audio power amplifier produced by Texas Instruments. It features advanced functionalities such as volume control, dynamic range compression (DRC), and automatic gain control (AGC). Available in both a 2.2 mm × 2.2 mm DSBGA package and a 20-pin QFN package, this amplifier is designed for high-efficiency audio applications without the need for output LC filters. The device is particularly suited for portable applications, including cellular handsets, PDAs, portable navigation devices, and notebook PCs, due to its small package size and fast start-up time.
