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