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 1.6Ω).

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.
