NTE1627
Integrated Circuit
Power Amp, 550mW, for Battery Operated Radios
Description:
The NTE1627 is a monolithic integrated circuit in a 9–Lead 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 8Ω. A maximum output power of 550mW is attainable.
Features:
D Delivers 350mW (THD = 10%) of Output Power to a 8Ω Load with 6V Operation
D Excellent Low–Voltage Characteristics (Starting Voltage < 2V)
D Housed in a Compact 9–Lead SIP Package Comparable in Size to a Preamplifier IC
D Low Current Consumption (Typically 4.8mA)
Applications:
D Portable Radios
D Portable Tape Recorders
D Intercoms
