Lead free / RoHS Compliant
Description:
The NTE864 is a precision waveform generator in a 14-Lead DIP type package capable of producing
high accuracy sine, square, triangular, sawtooth and pulse waveforms. The frequency (or repetition
rate) can be selected externally from 0.001Hz to 300kHz. The frequency of oscillation is highly stable
over a wide range of temperature and supply voltage changes. Both full frequency sweeping as well
as smaller frequency variations (FM) can be accomplished with an external control voltage. Each of
the three basic waveforms, i.e., sinewave, triangle and square wave outputs are available simulta‐
neously.
Applications:
D Low Frequency Drift with Temperature: 250ppm/°C
D Low Distortion: 1% (Sinewave Output)
D High Linearity: 0.1% (Triangle Wave Output)
D Wide Frequency Range: 0.001Hz to 300kHz
D variable Duty Cycle: 2% to 98%
D High Level Outputs: TTL to 28V
D Simultaneous Sine, Square, and Triangle Wave Outputs
