Yesterday, I decided to mess around with the DG4354 chip. I’d seen some stuff about it online, and it seemed like a fun little project to kill an afternoon. So, I grabbed my tools and got started.
Getting Started
First things first, I needed to gather all my supplies. I already had the DG4354, of course. Then I dug out my trusty breadboard, some jumper wires, a power supply, and my multimeter – can’t forget that!
- DG4354 Chip
- Breadboard
- Jumper Wires (a bunch of different colors)
- Power Supply (I set it to 5V)
- Multimeter
Wiring it Up
Okay, time to connect everything. I found a simple schematic online, nothing too crazy. I carefully placed the DG4354 onto the breadboard, making sure each pin was in its own row. Then, I started connecting the power. I used a red wire for the positive (+) and a black wire for the ground (-), just to keep things organized. I double-checked everything with the schematic, just in case…I hate frying circuits and had smoke come out.
Next, I wired up the control pins. These are the pins that actually tell the DG4354 what to do.I use difference colors with jumper wires to breadboard,so that I won’t mess up.
Testing it Out
With everything wired up, it was time for the moment of truth. I connected the power supply and turned it on. Nothing exploded, which is always a good sign! Then, I used my multimeter to check the voltages at various points on the circuit, just to make sure everything was getting the right amount of power. Everything looked good.
The Actual Thing
I flipped the control switch, and… I tested it with the multimeter again. Yep, it worked! It was doing exactly what I wanted. I played around with it for a while, changing the inputs and watching the outputs change.
I put the signal input to the breadboard,and observe the waveform with oscilloscope,it does change following what I expected,all good!
Wrapping Up
In the end, the whole thing took me a couple of hours. It was a pretty smooth process, and I’m happy with how it turned out. I learned something, which is the main goal, and I got to play with some electronics. I could build more project based on * bad for a simple experiment!
