National Semiconductor LM2896 Manuals

LM1896 and LM2896 are high-performance 6V stereo power amplifiers that can deliver 1 watt per channel or 2 watts bridged monaural power. It utilizes a unique patented compensation scheme and is ideal for sensitive AM radio applications. The amplifier has a wide supply range of 3V–9V, making it suitable for battery operation. The LM2896 is available for higher supply voltages (greater than 9V). The product features low AM radiation, low noise, low distortion, no turn-on 'pop' sound, adjustable voltage gain and bandwidth, and smooth waveform clipping. It is suitable for compact AM-FM radios, stereo tape recorders and players, and high-power portable stereos.

The LM1896 is a high performance 6V stereo power amplifier designed to deliver 1 watt per 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 > 9V), the LM2896 is available in an 11-lead single-in-line package. The LM2896 package has been redesigned, resulting in slightly degraded thermal characteristics shown in Figure 2.
