Powered by a flexible 3.5-24V DC supply and featuring two adjustable potentiometers for precise control, this 4-pack set is ideal for professionals and hobbyists seeking reliable, customizable signal amplification in a sleek form factor. ## Description Description: 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: the default of this LM358 Amplifier is 1000 times. Parameters: 1. Power supply voltage: 3.5-24V DC power supply 2. Current output: maximum 15-20MA (non-linear) 3. Voltage output: output = input voltage signal * magnification 4. Magnification: Total multiple = first multiple multiple * second multiple multiple 5. Board size: length 45.3mm width 16.2mm 6. The two potentiometers on the board are rotated counterclockwise to increase the multiple. Package included: 4* LM358 Weak Signal Amplifier Boards ## Features - LM358 Weak Signal Amplifier Voltage Amplifier 3.5-24V DC - LM358 is the core two-stage operational amplifier, which can amplify DC weak signals. - Two potentiometers on the board are rotated counterclockwise to increase the multiple. - It amplify signals of millivolts or even weaker, and has two potentiometers to be rotated counterclockwise to increase the multiple. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09KGW36Q8 | | Best Sellers Rank | #131,557 in Electronics ( See Top 100 in Electronics ) #788 in Audio Component Amplifiers | | Brand Name | HiLetgo | | Customer Reviews | 4.1 4.1 out of 5 stars (14) | | Manufacturer | HiLetgo | | Maximum Supply Voltage | 24 volts_of_direct_current | | Minimum Supply Voltage | 3.5 volts_of_direct_current | | Model | LM358 | | Mounting Type | Surface Mount | | Number of Channels | 4 | | Number of Items | 4 | | Number of Packs | 4 | | Package Type Name | box" or "padded envelope | | Part Number | 3-01-1718 | | Specification Met | [Possibly] Fcc | | Unit Count | 4 Count | | Voltage | 24 volts | ## Product Details - **Manufacturer:** HiLetgo - **Maximum Supply Voltage:** 24 volts_of_direct_current - **Minimum Supply Voltage:** 3.5 volts_of_direct_current - **Mounting Type:** Surface Mount - **Voltage:** 24 volts ## Images ![HiLetgo 4pcs LM358 Weak Signal Voltage Amplifier Secondary Operational Amplifier Board Module Single Power Signal Collector 3.5-24V - Image 1](https://m.media-amazon.com/images/I/51iPd0lJIpL.jpg) ![HiLetgo 4pcs LM358 Weak Signal Voltage Amplifier Secondary Operational Amplifier Board Module Single Power Signal Collector 3.5-24V - Image 2](https://m.media-amazon.com/images/I/41Cmop31rPL.jpg) ![HiLetgo 4pcs LM358 Weak Signal Voltage Amplifier Secondary Operational Amplifier Board Module Single Power Signal Collector 3.5-24V - Image 3](https://m.media-amazon.com/images/I/41OVdOJwtjL.jpg) ![HiLetgo 4pcs LM358 Weak Signal Voltage Amplifier Secondary Operational Amplifier Board Module Single Power Signal Collector 3.5-24V - Image 4](https://m.media-amazon.com/images/I/41TSFBjfX9L.jpg) ![HiLetgo 4pcs LM358 Weak Signal Voltage Amplifier Secondary Operational Amplifier Board Module Single Power Signal Collector 3.5-24V - Image 5](https://m.media-amazon.com/images/I/41P-9z-lGWL.jpg) --- ## 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.kg/products/470876258-hiletgo-4pcs-lm358-weak-signal-voltage-amplifier-secondary-operational-amplifier](https://www.desertcart.kg/products/470876258-hiletgo-4pcs-lm358-weak-signal-voltage-amplifier-secondary-operational-amplifier) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-09-03*
