LM358 is the core two-stage operational amplifier, which can amplify DC weak signals, such as DC voltage signals, DC pulse signals, can amplify signals of millivolts or even weaker, and has two potentiometers, respectively for the first stage and The second stage performs single-stage magnification adjustment, but the total magnification is the product of the two-stage multiple, so the magnification will be adjusted to a large extent.(If the first level is adjusted to 20 times magnification, then if the second level is adjusted to 100 times, then the total magnification is 2000 times)Note: If the friends take the maximum magnification without telling the request, we will ship the goods at the default 1000 times.Board parameters:1. Power supply voltage: 3.5-24V DC power supply2. Current output: maximum 15-20MA (non-linear)3. Voltage output: output = input voltage signal * magnification4. Magnification: Total multiple = first multiple multiple * second multiple multiple5. Board size: length 45.3mm width 16.2mm6. The two potentiometers on the board are rotated counterclockwise to increase the multiple.
The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
