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.
