Product Description:
1.ICL8038 Multi-function Low Frequency Signal Generator Kit is a monolithic integrated circuit chip made of Schottky barrier diode and other advanced processes, wide range of supply voltage, high stability, high precision, easy to use, etc., the external access to very few components to work, can simultaneously generate square, triangle and sine waves, the frequency of its function waveforms are controlled by the internal or external voltage, can be applied to voltage-controlled Oscillation and FSK modulator.
2. With a low frequency drift in the occurrence of temperature changes, the maximum does not exceed 50PPM / C; with a sine wave, triangle wave and square wave and other Western signal output; sine wave output with less than 1% distortion; triangle wave output with 0.1% high linearity; with a frequency output range of 5HZ ~ 400KHZ; the work of a wide period of change, 2% ~ 95% arbitrarily adjustable: high level output range, from TTL level to 28V; easy to use, only need few external conditions.
3, ICL8038 is a precision oscillator IC with a variety of waveform outputs, only need to adjust the individual external components can be generated from 0.001HZ ~ 300kHz low-distortion sine wave, triangle wave, rectangular wave and other pulse signals. The frequency and duty cycle of the output waveform can be controlled by current or resistance. In addition, since the chip has an FM signal input, it can be used to modulate the frequency of low-frequency signals.
