LM358 Voltage Amplifier Module MusRock 10pcs 1 to 100x Gain 4.5-36V

Description

Product Overview

The LM358 Voltage Amplifier Module from MusRock is engineered for high‑precision signal amplification in demanding electronic applications. Featuring a broad input voltage range of 4.5 to 36 volts, the module can accommodate a variety of power supplies, from low‑cost battery packs to regulated laboratory sources. Its onboard 10 kΩ potentiometer enables seamless gain adjustment from 1× up to 100×, allowing users to fine‑tune amplification without external components. The design incorporates a DC‑coupled input stage, ensuring that both AC and DC signals are faithfully reproduced with minimal distortion.

Robust construction is a hallmark of this module. The PCB layout follows industry‑standard spacing and shielding practices, while the screw‑terminal interface provides secure, tool‑free connections for rapid prototyping. Operating temperature spans from –40 °C to +85 °C, guaranteeing reliable performance in harsh industrial environments, automotive test rigs, and outdoor field equipment. The module’s static current stays below 5 mA, and a dedicated sleep mode reduces consumption to just 1.8 µA, making it suitable for long‑term battery‑operated deployments.

Usage

Designed with versatility in mind, this amplifier module fits seamlessly into a range of projects. Engineers working with STM32 microcontrollers can connect the module directly to analog input pins, using the adjustable gain to match sensor output levels. Researchers employing MATLAB for data acquisition benefit from the module’s stable bandwidth up to 100 kHz, enabling accurate capture of fast‑changing signals. The compact 32.7 mm × 13.3 mm footprint allows integration into dense PCB layouts, while the wide voltage tolerance supports both low‑power IoT devices and high‑voltage instrumentation.

Typical use cases include conditioning signals from strain gauges, thermocouples, and photodiodes, where weak outputs require amplification before digitization. The module also excels in audio pre‑amplification, providing clean gain for microphone inputs in portable recording rigs. Its temperature‑resilient design ensures consistent performance whether mounted inside a climate‑controlled lab bench or exposed to outdoor temperature fluctuations.

FAQ

What is the maximum bandwidth of the LM358 module?

The module maintains a flat frequency response up to 100 kHz, making it suitable for most low‑frequency sensor and audio applications.

Can the module be powered from a single 5 V supply?

Yes, the LM358 operates correctly with a supply voltage as low as 4.5 V, so a standard 5 V USB or battery source is sufficient.

Is the gain adjustment linear across the entire range?

The onboard potentiometer provides smooth, near‑linear gain control from 1× to 100×, with a gain error of ±0.05 % full‑scale, ensuring accurate amplification.

How do I connect the module to an STM32 board?

Use the screw‑terminal pins to link the module’s input to the STM32’s analog pin, and connect the power pins to the board’s 5 V and ground. Configure the ADC sampling rate to match the module’s 100 kHz bandwidth for optimal results.

What warranty does MusRock offer for this product?

Each LM358 Amplifier Module is covered by a 12‑month limited warranty that protects against manufacturing defects, and MusRock’s support team is available for troubleshooting throughout the warranty period.
