The NTE1851 is a monolithic integrated class-B amplifier from NTE Electronics, housed in a 13-lead Staggered SIP package. It is primarily developed for car radio applications and can drive low-impedance loads down to 1.6 ohms.
This audio amplifier delivers high output power, with up to 24W in BTL (Bridge-Tied Load) configuration at a supply voltage of 14.4V into a 4-ohm load. When used as a stereo amplifier, it provides 2 x 11W into 2 ohms or 2 x 6.5W into 4 ohms. The device features a fixed gain of 20dB, low offset voltage at the output, and good ripple rejection.
Key features include flexibility in use for mono BTL or stereo configurations, load dump protection, AC and DC short-circuit safety to ground up to 18V, and thermal protection. It also offers speaker protection in bridge configuration and SOAR protection. The NTE1851 is designed for high reliability and requires a low number of external components, simplifying integration into designs.
Applications include car radio systems and driving low impedance loads. The NTE1851 is mounted using a through-hole method.
