Overview
The TPA6211A1DGNR is a 3.1-W mono, fully differential, Class-AB audio power amplifier designed by Texas Instruments. This device is optimized for use in wireless handsets, PDAs, and other portable electronic devices. It operates from a supply voltage range of 2.5 V to 5.5 V, making it suitable for direct battery operation. The amplifier is known for its low quiescent supply current of 4 mA at 5 V and a shutdown current of 0.01 µA, which helps in conserving battery life. The TPA6211A1DGNR is available in space-saving packages, including the 8-pin MSOP-PowerPAD (DGN) and the 3-mm × 3-mm SON (DRB), making it ideal for applications where board space is limited.
