General Description

The LM1896 is a high performance 6V stereo power amplifier designed to deliver 1 watt channel into 4X or 2 watts bridged monaural into 8X Utilizing a unique patented compensation scheme the LM1896 is ideal for sensitive AM radio applications This new circuit technique exhibits lower wideband noise lower distortion and less AM radiation than conventional designs The amplifier’s wide supply range (3V – 9V) is ideal for battery operation For higher supplies (VS l 9V) the LM2896 is available in an 11-lead single-inline package The LM2896 package has been redesigned resulting in the slightly degraded thermal characteristics shown in the figure Device Dissipation vs Ambient Temperature
