LM1877 www.ti.com SNAS550B – FEBRUARY 1995 – REVISED APRIL 2013 LM1877 Dual Audio Power Amplifier Check for Samples: LM1877 FEATURES DESCRIPTION • • • • • • • • The LM1877 is a monolithic dual power amplifier designed to deliver 2W/channel continuous into 8Ω loads. The LM1877 is designed to operate with a low number of external components, and still provide flexibility for use in stereo phonographs, tape recorders and AM-FM stereo receivers. Each power amplifier is biased from a common internal regulator to provide high power supply rejection, and output Q point centering. The LM1877 is internally compensated for all gains greater than 10. 1 2 2W/Channel −65 dB Ripple Rejection, Output Referred −65 dB Channel Separation, Output Referred Wide Supply Range, 6V–24V Very Low Cross-Over Distortion Low Audio Band Noise AC Short Circuit Protected Internal Thermal Shutdown APPLICATIONS • • • • • • • Multi-Channel Audio Systems Stereo Phonographs Tape Recorders and Players AM-FM Radio Receivers Servo Amplifiers Intercom Systems Automotive Products Connection Diagram Figure 1. 14-Pin SOIC or PDIP (Top View) See NPA0014B or NFF0014A Package 1 2 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.
