Lm2878 Dual 5 Watt Power Audio Amplifier - National Semiconductor

The LM2878 is a high voltage stereo power Amplifier de- signed 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 components, and still provide flexibility for use in stereo phonographs, tape recorders, and AM-FM stereo receivers. The flexibility of the LM2878 al- lows it to be used as a power Operational Amplifier power Comparator or servo Amplifier The LM2878 is internally compensated for all gains greater than 10, and comes in an 11-lead single-in-line package (SIP). The package has been redesigned, resulting in the slightly degraded thermal char- acteristics shown in the figure Device Dissipation vs Ambi- ent Temperature. By National Semiconductor Corporation
