www.ti.com SNAS494D – JANUARY 2010 – REVISED MAY 2013 LM48312 Boomer™ Audio Power Amplifier Series 2.6W, Ultra-Low EMI, Filterless, Mono
Class D Audio Power Amplifier with E2S
Check for Samples: LM48312 FEATURES DESCRIPTION The LM48312 is a single supply, high efficiency,
mono, 2.6W, filterless switching audio amplifier. The
LM48312 features TI’s Enhanced Emissions
Suppression (E2S) system, that features a unique
patented ultra low EMI, spread spectrum, PWM
architecture, that significantly reduces RF emissions
while preserving audio quality and efficiency. The E2S
system improves battery life, reduces external
component count, board area consumption, and
system cost, simplifying design. 1 23 Passes FCC Class B Radiated Emissions with
20 Inches of Cable
E2S System Reduces EMI While Preserving
Audio Quality and Efficiency
Output Short Circuit Protection with AutoRecovery
No Output Filter Required
Improved Audio Quality
Minimum External Components
Five Logic Selectable Gain Settings (0, 3, 6, 9,
12dB)
Low Power Shutdown Mode ...
