NTE7051
Integrated Circuit
1W BTL Mono Audio Amplifier
Description:
The NTE7051 is a mono output amplifier in a 8鈥揕ead DIP style plastic package designed for use in
battery鈥揻ed portable audio applications, such as tape recorders and radios.
This device uses the Bridge鈥揟ied鈥揕oad principle (BTL) which can deliver an output power of 1.2W
(THD = 10%) into an 8鈩?load with a power supply of 6V. The load can be short鈥揷ircuited at each signal
excursion.
