LM4853 www.ti.com SNAS155E JANUARY 2002REVISED MAY 2013 LM4853 Mono 1.5 W / Stereo 300mW Power Amplifier Check for Samples: LM4853 1FEATURES DESCRIPTION The LM4853 is an audio power amplifier capable of 2 Mono 1.5W BTL or Stereo 300mW Output delivering 1.5W (typ) of continuous average power Headphone Sense into a mono 4 bridged-tied load (BTL) with 1% Click and Pop Suppression Circuitry THD+N or 95mW per channel of continuous average power into stereo 32 single-ended (SE) loads with No Bootstrap Capacitors Required 1% THD+N, using a 5V power supply. Thermal Shutdown Protection The LM4853 can automatically switch between mono Unity-Gain Stable BTL and stereo SE modes utilizing a headphone Available in Space-Saving VSSOP and WSON sense pin. It is ideal for any system that provides Packaging both a monaural speaker output and a stereo line or headphone output APPLICATIONS Boomer audio power amplifiers were designed Portable Computers specifically to provide high quality output power with a minimal amount of external components. Since the Desktop Computers LM4853 does not require bootstrap capacitors or PDA s snubber networks, it is optimally suited for low-power Handheld Games portable systems. The LM4853 features an externally controlled, KEY SPECIFICATIONS micropower consumption shutdown mode and Output Power at 1% THD+N, 1kHz: thermal shutdown protection. The unity-gain stable LM4853 s gain is set by external gain-setting resistors LM4853LD 3 BTL 1.9W (typ) LM4853LD 4 BTL 1.7W (typ) LM4853MM 4 BTL 1.5W (typ) LM4853MM,LD 8 BTL 1.1W (typ) LM4853MM,LD 8 SE 300mW (typ) LM4853MM,LD 32 SE 95mW (typ) THD+N at 1kHz, 95mW into 32 SE 1% (typ) Single Supply Operation 2.4 to 5.5V Shutdown Current 18A (typ) Connection Diagram Figure 1. 10 Lead VSSOP Top View Figure 2. 14 Lead WSON Top View See Package Number DGS See Package Number NHE0014A 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2All trademarks are the property of their respective owners.
