NTE1604 Datasheet | NTE Electronics

Description : The NTE1604 is an integrated circuit in a 16- Lead SIP type package designed for use in FM car stereo receivers. This device features versatile muting characteristics and allows receiver designers to realize the muting performance according to their design concept. Functions: D IF Amplification/Limiter D AFC Output D Muting Bandwidth D Quadrature Detector Signal Meter Output Muting Under Weak Signal Strength AF Preamplifier AGC Output Features : D Versatile Mutings a. When Muting Operation is Performed under a Weak Signal Strength, an Attenuation Slope of the Audio Output Against the Input Signal Strength Varaitions can be Set at any Given value b. Maximum Muting Attenuation can be Selected Between about 6d B to 40d B c. Input Signal Strength level which Actuates the Muting Circuit can be Set Freely D High Limiting Sensitivity (25dbµ Typ. with Muting OFF) Provides a Fine Quieting Characteristic D High Signal- to- Noise Ratio: 78d B Typ D Low Distortion (0.05% Typ) Available, if used with Double- Tuned Circuits D Good AM Rejection Ratio (63d B with 6 Stages of Differential IF Amplifiers) D Signal Merter Drive Output Proportional to the Input Signal Strength in d B D Clamped (±VBE) AFC Output, Bandwidth Adjustable D Delayed AGC Output for Front End Circuit Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Maximum Supply Voltage (Pin12), VCCmax - - - - - - - - . . . . 16V Maximum Supply Current (Pin12), ICCmax - - - - - - - - . . . 40m A Allowable Power Dissipation, PDmax TA = +25°C - - - - - - - - - - - - . . . 640m W TA = +70°C - - - - - - - - - - - - . . . 460m W Input Voltage (Pin1 to Pin2), vi - - -...
