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 1.6Ω).
At a supply voltage V_CC = 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.
