LM1896/LM2896 Dual Audio Power Amplifier
General Description
The LM1896 is a high performance 6V stereo power amplifi-
er designed to deliver 1 watt/channel into 4
X
or 2 watts
bridged monaural into 8
X
. Utilizing a unique patented com-
pensation 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
(V
S
l
9V) the LM2896 is available in an 11-lead single-in-
line package. The LM2896 package has been redesigned,
resulting in the slightly degraded thermal characteristics
shown in the figure Device Dissipation vs Ambient Tempera-
ture.
