NTE1486
Integrated Circuit
FM/AM Tuner System
Description:
The NTE1486 is an integrated circuit in a 16+2−Lead DIP type package designed for use in stereo
applications. This high performance device integrates all the functions necessary for FM IF and
detection by AM IF amplifiers.
Functions:
FM
D IF Amplifier
D Detector Circuit
D Low Noise Audio Amplifier
D Signal Meter Circuit
D Center Meter Circuit
D Muting Circuit
D AFC Circuit
AM
D IF Amplifier
D AGC Circuit
Features:
D Labor Saving and Miniaturization are Possible, since the FM IF Amplifier Detection and AM IF
Amplifiers are Enclosed in the Same Package.
D FM IF Amplifiers have High Stability due to the Adoption of the Full Balance Three Stage Direct
Coupled Differential Amplifier.
D Utilizes the Quadrature Detection Circuit.
D High Sensitivity (Input limiting sensitivity: 15V Typ)
D Large Detection Output: 450mV_rms Typ @ 100% modulation
D Low Distortion Factor: 0.04% Typ, when the double tuning detection coil is used
D High Signal−to−Noise Ratio: 79dB Typ
D Muting Circuit which does not Produce the Unbalance at Right or Left when Detuning.
D Muting Attenuation is Large: 80dB Typ
D AM Rejection Ratio is Good: 55dB @ 100dBμ Input
D Signal−to−Noise Ratio of AM IF is Good: 50dB @ 64dBμ Input
D AGC FOM of AM IF is Good: 48dB
D Electrodynamic Range for the Input of the Signal Meter is Large: 43dBμ to 115dBμ Typ
