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:

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

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_rmsTyp @ 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

Absolute Maximum Ratings: (T_A= +25°C unless otherwise specified)
