Product Summary

The TPA6211A1DGNR is a 3.1-W mono fully-differential amplifier designed to drive a speaker with at least 3- Ω impedance while consuming only 20 mm 2 total printed-circuit board (PCB) area in most applications. The TPA6211A1DGNR operates from 2.5 V to 5.5 V, drawing only 4 mA of quiescent supply current. The TPA6211A1DGNR is available in the space-saving 3-mm × 3-mm QFN (DRB) and the 8-pin MSOP (DGN) PowerPAD packages. The TPA6211A1DGNR is ideal for Wireless Handsets, PDAs, and Notebook Computers.
