NTE NTE1368

NTE1368
Integrated Circuit
Dual Audio Power Amplifier, 5.8W/Channel
Description:
The NTE1368 is an integrated circuit in a 12–Lead SIP type package designed for dual, low–frequency,
high power amplifier applications. This device requires few external components, thus enabling high
density mounting. Design for heat radiation is easy due to low thermal resistance. The NTE1368
contains internal power–on pop noise protection circuitry and various other protection circuits. This
device is best suited for car stereo applications.
