With a frequency range of 50-5KHz and a 12V DC input, this compact module is perfect for both hobbyists and professionals looking to explore the world of signal generation. ## Description Description: ICL8038 pin functions: Pin 1, Pin 12: sine waveform adjusting terminal; Pin 2: sine wave output; Pin 3: triangle wave output; Pin 4, Pin 5: the frequency and duty cycle (or waveform asymmetry) adjustment; Pin 6: V +, the positive power supply; Pin 7: Frequency Offset; Pin 8: Frequency adjustment input terminal; Pin 9: 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; Pin 10: timing capacitor terminal; Pin 11: V-, negative power supply terminal or the ground. When Use positive and negative power supply, Pin 11 to the negative supply, the output waveform are symmetrical with respect to 0 V; When use a single positive power supply, Pin 11 grounded, the output waveform is unipolar, uniform voltage is + VCC / 2; Pin 13 and Pin 14: Empty Pin. The kit is designed for a frequency range is 50-5KHz, two bands with using 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. Model: ICL8038 Input: 12V DC Frequency range: 50-5KHz, Package Included: 1 * ICL8038 Function Signal Generator DIY KIT Note: Please contact us if you need the Schematic. ## Features - ICL8038 Monolithic Function Signal Generator Module DIY Kit - Frequency range: 50-5KHz, - Input: 12V DC - Model: ICL8038 - uniform voltage is + VCC / 2 ## Images ![HiLetgo 2pcs ICL8038 Monolithic Function Signal Generator Module DIY Kit Sine Square Triangle - Image 1](https://m.media-amazon.com/images/I/61CGZRoEDvL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Chip works fine in my circuit *by M***E on July 14, 2024* Ended up just using the chip in a circuit board of my design with better THD specs. Got THD down to 0.8%. This chip is only made as an offshore copy, and this one worked fine ### ⭐⭐⭐⭐⭐ Nice generator little noisy making the scope jump every now and then. *by I***E on February 4, 2024* Went together pretty easy. Tried to put it together fast but I didn't like the way the tags on the solder joints look but I have another to assemble for a later date. Real easy to dial in. 50hz holds pretty well and with the low end dialed in the upper end reaches 5.2khz. One thing i did notice is that the scope will jump every now and then where this didn't happen to the other generator i built yesterday. I'm thinking one of the caps may be junk. Anywho its giving me soldering time and another excuse to buy a new station.It works and I like it... ### ⭐⭐ fun, but no stable output *by A***I on February 25, 2025* The media could not be loaded. only useful as a solder practicing kit. frequency generated is extremely unstable, and it is near impossible to tune it in. the positions of adjustment potentiometers in circuit (course and fine in parallel) is a bit suspicious, maybe that has something to do with it, but I'm not going to spend time troubleshooting it. ## Frequently Bought Together - HiLetgo 2pcs ICL8038 Monolithic Function Signal Generator Module DIY Kit Sine Square Triangle - Signal Generator Kit, XR2206 Precise Function Signal Generator Frequency Module DIY Kit Sine Triangle Square Output Adjustable 1Hz-1MHz, 9-12V Direct Current Input(1 Piece) - FNIRSI DSO152 Oscilloscope - 2.8" TFT Handheld Digital Oscilloscope Kit Portable Oscilloscope, 2.5MS/s High Sampling Rate, 200KHz Bandwidth, Trigger Function Auto/Nomal/Single --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fi/products/39929633-hiletgo-2pcs-icl8038-monolithic-function-signal-generator-module-diy-kit](https://www.desertcart.fi/products/39929633-hiletgo-2pcs-icl8038-monolithic-function-signal-generator-module-diy-kit) --- *Product available on Desertcart Finland* *Store origin: FI* *Last updated: 2026-05-05*
