วงจรกำเนิดสัญญาณความถี่ ICL8038 Low Frequency Sine,Square, Triangle Wave Signal Generator Module Source Monolithic ICs The ICL8038 waveform generator generates high-precision sine, square, triangular, sawtooth, and pulsed waveforms with a small number of external components. Selecting a different external resistor or capacitor yields signals at any frequency from 0.001Hz to 300kHz with a duty cycle range of 2% to 98%. ICL8038 can also produce FM signal, frequency modulation and scanning can be done by an external voltage. ICL8038 internal Schottky barrier diodes and thin film resistors, the use of advanced monolithic integrated manufacturing technology, so the output signal can be in a wide range of temperature and power to maintain a stable range, the sine wave output signal distortion rate can be Low to 1%, triangular wave output signal linear distortion can be as low as 0.1%. ICL8038 temperature drift can be less than 250ppm / ° C. The figure below shows the ICL8038 external pin diagram. Pin (1) and (12) are sine wave adjustment, pin (2) is sine wave output, pin (3) is triangular wave output, pin (4) and pin (5) (6) is the positive power supply input pin, (7) is the frequency adjustment bias voltage output port, can output a bias voltage proportional to the power supply voltage, pin (8) is (9) is the square wave, the pulse wave output end, the pin (10), the output terminal of the pulse (10), and the output signal of the voltage ) Is the access terminal of the timing capacitor. The pin (11) is the negative power supply input terminal. When using a single power supply, this terminal is grounded. Pins (13) and (14) are empty pins and are not intended for electrical connection.
