Product Overview
The Texas Instruments TPA0211DGNR is a 2-W mono Class-AB audio power amplifier in a thermally-enhanced 8-pin HVSSOP (MSOP-PowerPAD) package. Capable of driving 2 W into a 4 Ω speaker from a 5 V supply, it supports both BTL (bridge-tied-load) speaker drive and single-ended headphone output. The device features a shutdown mode with 1 µA typical current and wide supply compatibility from 2.5 V to 5.5 V.
