NTE1627
Integrated Circuit
Power Amp, 550mW, for Battery Operated Radios
Description:
The NTE1627 is a monolithic integrated circuit in a 9鈥揕ead SIP type package consisting of a power
amplifier intended for applications such as portable radios, tape recorders, and intercoms. It operates
from a supply voltage of 6V and can deliver the rated output power of 350mW (THD = 10%) to a load
of 8鈩? A maximum output power of 550mW is attainable.
