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
bridged monaural into 8
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
