LM2878 Datasheet | National Semiconductor

Description The LM2878 is a high voltage stereo power amplifier designed to deliver 5W channel continuous into 8X loads The amplifier is ideal for use with low regulation power supplies due to the absolute maximum rating of 35V and its superior power supply rejection The LM2878 is designed to operate with a low number of external ponents and still provide flexibility for use in stereo phonographs tape recorders and AM-FM stereo receivers The flexibility of the LM2878 allows it to be used as a power operational amplifier power parator or servo amplifier The LM2878 is internally pensated for all gains greater than 10 and es in an 11-lead single-in-line package (SIP) The package has been redesigned resulting in the slightly degraded thermal characteristics shown in the figure Device Dissipation vs Ambient Temperature Features Y Y Y Y Y Y Y Wide operating range 6V - 32V 5W channel output 60 d B ripple rejection output referred 70 d B channel separation output referred Low crossover distortion AC short circuit protected Internal thermal shutdown Applications Stereo phonographs AM-FM radio receivers Power op amp power parator Servo amplifiers Typical Applications Frequency Response of Bass Tone Control TL H 7934 - 2 TL H 7934 - 1 FIGURE 1 Stereo Phonograph Amplifier with Bass Tone Control C1995 National Semiconductor Corporation TL H 7934 RRD-B30M115 Printed in U S A Absolute Maximum Ratings If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Supply Voltage Input Voltage (Note 1) Operating Temperature (Note 2) 35V g 0 7V 0 C to a 70 C Storage Temperature Junction Temperature Lead Temperature (Soldering 10 sec ) Thermal Resistance i JC i JA b 65 C to a 150 C a 150 C a 260 C 10 C W 55 C W Electrical Characteristics VS e 22V Parameter Total Supply Current Operating Supply Voltage Output Power Channel Distortion PO e 0W TTAB e 25 C RL e 8X AV e 50 (34...
