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.

Features:

• Labor Saving and Miniaturization are Possible, since the FM IF Amplifier Detection and AM IF Amplifiers are Enclosed in the Same Package.

• FM IF Amplifiers have High Stability due to the Adoption of the Full Balance Three Stage Direct Coupled Differential Amplifier.

• Utilizes the Quadrature Detection Circuit.

• High Sensitivity (Input limiting sensitivity: 15V Typ)

• Large Detection Output: 450mVrms Typ @ 100 modulation

• Low Distortion Factor: 0.04 Typ, when the double tuning detection coil is used

• High Signal−to−Noise Ratio: 79dB Typ

• Muting Circuit which does not Produce the Unbalance at Right or Left when Detuning.

• Muting Attenuation is Large: 80dB Typ

• AM Rejection Ratio is Good: 55dB @ 100dBμ Input

• Signal−to−Noise Ratio of AM IF is Good: 50dB @ 64dBμ Input

• AGC FOM of AM IF is Good: 48dB

• Electrodynamic Range for the Input of the Signal Meter is Large: 43dBμ to 115dBμ Typ
