NTE787
Integrated Circuit
AM Receiver Subsystem
For Applications in a variety of AM broadcast and communications receivers and applications
requiring an array of amplifiers.
Description:
The NTE787, a monolithic integrated circuit, is an AM subsystem that provides the converter, IF ampli-
fier, detector, and audio preamplifier stages for an AM receiver. It also provides internal AGC for the
first IF amplifier stage, delayed AGC for an optional external RF amplifier, a buffer stage to drive a
tuning meter, and terminals facilitating the optional use of a tone control.
This device features four independent transistor amplifiers, each incorporating internal biasing for
temperature tracking. These amplifiers are particularly useful in general–purpose amplifier, oscillator,
and detector applications in a wide variety of equipment designs.
The NTE787 utilizes a 16–Lead DIP package and operates over an ambient temperature range of
–40° to +85°C.
