TPA6211A1 - 3.1-W Mono, Fully Differential, Class-AB Audio Amplifier

Updated : 2020-01-09 14:23:54

Description

The TPA6211A1 is a 3.1-W mono fully-differential amplifier designed to drive a speaker with at least 3-Ω impedance while consuming only 20 mm² total printed-circuit board (PCB) area in most applications. The device operates from 2.5 V to 5.5 V, drawing only 4 mA of quiescent supply current. The TPA6211A1 is available in the space-saving 3-mm × 3-mm SON (DRB) and the 8-pin MSOP-PowerPAD (DGN) packages.

Features like –80 dB supply voltage rejection from 20 Hz to 2 kHz, improved RF rectification immunity, small PCB area, and a fast startup with minimal pop makes the TPA6211A1 ideal for PDA and smart phone applications.
