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.)
