NTE1093
Integrated Circuit
High Gain, 1W, Audio Amplifier
Description:
The NTE1093 is a monolithic integrated circuit consisting of a high gain direct−coupled 2 stage preamplifier and 1W AF output pushpull power amplifier. It is designed for use in portable tape recorders
and radios where low voltage operation and low power consumption is required.
