www.ti.com SNAS095C – MAY 1997 – REVISED MAY 2013 LM4861 1.1W Audio Power Amplifier with Shutdown Mode
Check for Samples: LM4861 FEATURES DESCRIPTION The LM4861 is a bridge-connected audio power
amplifier capable of delivering 1.1W of continuous
average power to an 8О© load with 1% THD+N using
a 5V power supply. 1 2 No output coupling capacitors, bootstrap
capacitors, or snubber circuits are necessary
Small Outline (SOIC) packaging
Compatible with PC power supplies
Thermal shutdown protection circuitry
Unity-gain stable
External gain configuration capability APPLICATIONS Personal computers
Portable consumer products
Self-powered speakers
Toys and games The LM4861 features an externally controlled, lowpower consumption shutdown mode, as well as an
internal thermal shutdown protection mechanism. KEY SPECIFICATIONS Boomer audio power amplifiers were designed
specifically to provide high quality output power with a
minimal amount of external components using
surface mount packaging. Since the LM4861 does
not require output coupling capacitors, bootstrap
capacitors, or snubber networks, it is optimally suited
for low-power portable systems. THD+N for 1kHz at 1W continuous average
output power into 8Ω 1.0% (max) …
