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 foot, 14 Foot: Empty foot. The kits are designed for a frequency range is 50-5KHz, two bands with a switch S to switch, RP1 is the frequency adjustment, RP2 is the duty cycle adjustment, RP3 is a sine wave distortion adjustment. Circuit uses 12V single power supply, input from the X1; X2, X3 is a waveform output side, you can use oscilloscope to observe three output waveforms.Specification:Model: ICL8038 Input 12V DC Frequency range 50-5KHz, Size:6cm*4.5cm*0.2cm Weight:26gCircuit principle:
ICL8038 pin function:
1 pin, 12 pin: sine wave adjustment side
2 pin: sine wave output
3 pin: triangular wave output
4 pin, 5 pin: frequency and duty cycle (or waveform asymmetry) adjustment
6 pin: V +, positive power supply
7 pin: frequency offset
8 pin: frequency adjustment input
9 pin: square wave output. This is an open collector output. When working, connect a load resistor from the pin to the corresponding positive supply, to obtain a TTL-compatible square wave output, the load resistor must be connected to the + 5V supply.
10 pin: timing capacitor side
11 pin: V-, negative power supply terminal connect ground. When using positive and negative power supply, 11 pin connected to the negative power supply, the output waveform is relative to 0V symmetry. When using a single positive power supply, pin 11 is grounded and the output waveform is unipolar and the uniform voltage is + VCC / 2.
13 pin, 14 pin: empty pin
The frequency range is 10KHz-450KHz, divided into 5 bands, with switch J2 (short-circuit cap) to switch, PR1 is the frequency adjustment, RP2 is the square wave duty cycle adjustment, RP3 is the square wave linear adjustment, RP4 is the sine wave distortion adjustment, RP5 is the output amplitude adjustment.
The circuit can be powered from a single 12-24V supply from J1. J4 is the waveform output, 1 pin output with DC bias signal, 2 pin output pure signal, the output waveform category can be switch by J3 (short-circuit cap).
