NTE1851 Integrated Circuit Audio Amplifier, 24W BTL
Description: The NTE1851 is a monolithic integrated class-B amplifier in a 13-Lead Staggered SIP type package primarily developed for car radio applications, and also to drive low-impedance loads (down to 1.6). At a supply voltage VCC = 14.4V, an output power of 21W can be delivered into a 4 BTL (Bridge-Tied Load), or, when used as a stereo amplifier, it delivers 2 x 11W into 2 or 2 x 6.5W into 4. Features: D Flexibility In Use - Mono BTL as well as Stereo D D High Output Power D D Low Offset Voltage at the Output D (Important for BTL) D Large Usable Gain Variation D D Very Good Ripple Rejection D D Internal Limited Bandwidth for High Frequencies D D Low Standby Current Possiblity (1A Typ), to Simplify Required Switches: TTL Drive Possible D D Low Number of Small-Sized External Compo- D nents Applications: D Car Radio Applications D Drive Low Impedance Loads D Stereo Amplifier Absolute Maximum Ratings: Supply Voltage (Pin10), VCC Operating . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Non-Operating . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 28V Supply Voltage (During 50ms Load Dump Protection), VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 45V Peak Output Current, IOM . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8A Crystal Temperature, TC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +150C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -65 to +150C AC and DC Short-Circuit Safe Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Reverse Polarity . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10V
