NTE727
Integrated Circuit
Four Independent AC Amplifiers
Description:
The NTE727 is a silicon monolithic integrated circuit in a 16鈥揕ead DIP type package consisting of four
independent identical AC amplifiers which can operate from a single鈥揺nded power supply.
The amplifiers include internal DC bias and feedback to provide temperature鈥搒tabilized 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鈥搃nverting input, and a lower impedance inverting
input for the application of feedback. Two power鈥搒upply terminals and two ground terminals are pro-
vided to reduce internal and external coupling between amplifiers.
