LM1896 Datasheet | National Semiconductor

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 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 (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 Features Y Y Y Y Y Y Y Y Y Low AM radiation Low noise 3V 4X stereo Po e 250 m W Wide supply operation 3V - 15V (LM2896) Low distortion No turn on ‘‘pop’’ Adjustable voltage gain and bandwidth Smooth waveform clipping Po e 9W bridged LM2896 Applications Y Y Y pact AM-FM radios Stereo tape recorders and players High power portable stereos Typical Applications TL H 7920 - 1 FIGURE 1 LM2896 in Bridge Configuration (AV e 400 BW e 20 k Hz) Order Number LM1896N Order Number LM2896P See NS Package Number N14A See NS Package Number P11A C1995 National Semiconductor Corporation TL H 7920 RRD-B30M115 Printed in U S A Absolute Maximum Ratings If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Supply Voltage LM1896 LM2896 Operating Temperature (Note 1) Storage Temperature VS e 12V VS e 18V 0 C to a 70 C b 65 C to a 150 C Junction Temperature Lead Temperature (Soldering 10 sec ) Thermal Resistance i JC (DIP) i JA (DIP) i JC (SIP) i JA (SIP) 150 C 260 C 30 137 10 55 C C C C W W W W Electrical Characteristics Unless otherwise specified TA e 25 C AV e 200 (46 d B) For the LM1896 VS e 6V and RL e 4X For LM2896 TTAB e 25 C VS e 12V and RL e 8X Test circuit shown in Figure 2 Parameter Supply...
