The NTE7118 integrated circuit is a hifi power amplifier in a 9Lead SIP type package designed for use as a building block in radio, TV, and other audio applications. The high performance of the IC meets the requirements of digital sources (e.g. Compact Disc equipment). The NTE7118 is totally protected, the two output transistors both having tthermal and SOAR protection. This device also has a mute function that can be arranged for a period after poweron with a delay time fixed by external components. The NTE7118 device is intended for symmetrical power supplies but an asymmetrical supply may also be used.
