NTE832

NTE832 & NTE832SM Integrated Circuit Tone Decoder Description: The NTE832 and NTE832SM are general purpose tone decoders designed to provide a saturated transistor switch to GND when an input signal is present within the passband. The circuit consists of an I and Q detector driven by a voltage controlled oscillator which determines the center frequency of the decoder. External components are used to independently set center frequency, bandwidth, and output delay. Features: D Logic Compatible Output with 100mA Current Sinking Capability D Bandwidth Adjustment from 0 to 14% D Inherent Immunity to False Signals D High Stable Center Frequency D High Rejection of Out–Of–Band Signals and Noise D Center Frequency Adjustable from 0.01Hz to 500kHz D Frequecny Range Adjustable over 20:1 range by an External Resistor D Available in Standard 8–Lead DIP (NTE832) and Surface Mount SOIC–8 (NTE832SM) Applications: D Touch Tone Decoder D Precision Oscillator D Frequency Monitoring and Control D Wide Band FSK Demodulation D Communications Paging Decoders D Carrier Current Remote Controls D Ultrasonic Controls (Remote TV, etc.) Absolute Maximum Ratings: Operating Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10V Input Voltage, VIN . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –10V to VCC +0.5V Output Voltage, VO . . . . . . . . . . . . . . . . . . . ...
