www.ti.com SNAS103C – NOVEMBER 1995 – REVISED MAY 2013 LM4880 Dual 250 mW Audio Power Amplifier with
Shutdown Mode
Check for Samples: LM4880 FEATURES DESCRIPTION The LM4880 is a dual audio power amplifier capable
of delivering typically 250mW per channel of
continuous average power to an 8О© load with 0.1%
THD+N using a 5V power supply. 1 2 No Bootstrap Capacitors or Snubber Circuits
are Necessary
Small Outline (SOIC) and PDIP Packaging
Unity-Gain Stable
External Gain Configuration Capability APPLICATIONS Boomer audio power amplifiers were designed
specifically to provide high quality output power with a
minimal amount of external components using
surface mount packaging. Headphone Amplifier
Personal Computers
CD-ROM Players Since the LM4880 does not require bootstrap
capacitors or snubber networks, it is optimally suited
for low-power portable systems. KEY SPECIFICATIONS The LM4880 features an externally controlled, lowpower consumption shutdown mode, as well as an
internal thermal shutdown protection mechanism. THD+N at 1kHz at 200mW Continuous Average
Output Power into 8О©: 0.1% (max)
THD+N at 1kHz at 85mW Continuous Average
Output Power into 32О©: 0.1% (typ)
Output Power at 10% THD+N at 1kHz into 8О© …
