DAOKI Signal Generator Module Monolithic Function Waveform ICL8038 DIY Kit Sine Triangle Square Wave Signal DC 12V Output 7KHz 50Hz Adjustable Frequency 12V DC Power Male Jack Connector Cable

Specifications: Supply voltage: 12V DC Working current: 9mA PCB board size: 2.0 x 1.5" ICL8038 pin functions: 1 foot, 12 foot: sine waveform adjusting terminal; 2 foot: sine wave output; 3 foot: triangle wave output; 4 foot, 5 foot: the frequency and duty cycle (or waveform asymmetry) adjustment; 6 foot: V +, the positive power supply; 7 foot: offset; 8 foot: frequency adjustment input terminal; 9 foot: square wave output. This is an open collector output terminal, work should take a load resistor to the corresponding positive power supply terminal from the pin, to get a TTL-compatible square-wave output, the load resistance must be connected to + 5V power supply; 10 foot: timing capacitor terminal; 11 foot: V-, negative power supply terminal or the ground. Use positive and negative power supply, 11 feet to the negative supply, the output waveform are symmetrical with respect to 0V; use a single positive power supply, 11 feet grounded, the output waveform is unipolar, uniform voltage is + VCC / 2; 13 feet, 14 Feet: Empty foot. Package Included: 1 x ICL8038 Function Signal Generator DIY KIT 1 x 12V DC Power Male Jack Connector Cable
