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 1.6Ω). At a supply voltage VCC = 14.4V, an output power of 21W can be delivered into a 4Ω BTL (Bridge–Tied Load), or, when used as a stereo amplifier, it delivers 2 x 11W into 2Ω or 2 x 6.5W into 4Ω.

FEATUREs:
• Flexibility In Use – Mono BTL as well as Stereo
• High Output Power
• Low Offset Voltage at the Output (Important for BTL)
• Large Usable Gain Variation
• Very Good Ripple Rejection
• Internal Limited Bandwidth for High Frequencies
• Low Standby Current Possiblity (1µA Typ), to Simplify Required Switches: TTL Drive Possible
• Low Number of Small–Sized External Components
• High Reliability
• Load Dump Protection
• AC and DC Short–Circuit Safe to Ground up to VCC = 18V
• Thermal Protection
• Speaker Protection in Bridge Configuration
• SOAR Protection
• Outputs Short–Circuit Safe to Ground in BTL
• Reverse–Polarity Safe

APPLICATIONs:
• Car Radio Applications
• Drive Low Impedance Loads
• Stereo Amplifier
