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.
Features:
Excellent overload characteristics
AGC for IF amplifier
Buffered output signal for tuning meter
Internal Zener diode provides voltage regulation
Two IF amplifiers stages
Low–noise converter and first IF amplifier
Low harmonic distortion (THD)
Delayed AGC for RF amplifier
Terminals for optional inclusion of tone control
Operates from wide range of power supplies: V+ = 6 to 16 volts
Optional AC and/or DC feedback on wide–band amplifier
Array of amplifiers for general–purpose applications
Suitable for use with optional external RF stage, either MOS or bipolar
