LM2878 Dual 5 Watt Power Audio Amplifier
General 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 components, 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
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 characteristics
shown in the figure Device Dissipation vs Ambient
Temperature.
