Description:

The NTE727 is a silicon monolithic integrated circuit in a 16–Lead DIP type package consisting of four independent identical AC amplifiers which can operate from a single–ended power supply. The amplifiers include internal DC bias and feedback to provide temperature–stabilized operation. They may be used in a wide variety of AC applications in which operational amplifiers have previously been used. Each high gain amplifier has a high impedance non–inverting input, and a lower impedance inverting input for the application of feedback. Two power–supply terminals and two ground terminals are provided to reduce internal and external coupling between amplifiers.
