www.ti.com SNAS133D – FEBRUARY 2001 – REVISED MARCH 2013 LM4819
350mW Audio Power Amplifier with Shutdown Mode
Check for Samples: LM4819, LM4819MBD FEATURES DESCRIPTION The LM4819 is a mono bridged power amplifier that
is capable of delivering 350mWRMS output power into
a 16Ω load or 300mWRMS output power into an 8Ω
load with 10% THD+N from a 5V power supply. 1 2 WSON, SOIC, and VSSOP Surface Mount
Packaging
Switch On/Off Click Suppression
Unity-Gain Stable
Minimum External Components KEY SPECIFICATIONS THD+N at 1kHz, 350mW Continuous Average
Output Power into 16О©: 10% (max)
THD+N at 1kHz, 300mW Continuous Average
Output Power into 8О©: 10% (max)
Shutdown Current: 0.7ОјA (typ) APPLICATIONS The LM4819 Boomer audio power amplifier is
designed specifically to provide high quality output
power and minimize PCB area with surface mount
packaging and a minimal amount of external
components. Since the LM4819 does not require
output coupling capacitors, bootstrap capacitors or
snubber networks, it is optimally suited for low-power
portable applications.
The closed loop response of the unity-gain stable …
