Amplifier Module LM358 1000 Times Signal Gain
This LM358 Weak Signal Amplifier Module is designed to amplify very small DC voltage signals—such as those in the millivolt range—by up to 1000 times. It is ideal for applications that require signal amplification before further processing. The module features a two-stage amplification system, each stage adjustable using dedicated potentiometers, enabling fine control over the overall gain.
Package Includes:
- 1 x LM358 Weak Signal Voltage Amplifier Module (Dual Stage)
With its compact design, low noise operation, and low power consumption, the module is suitable for medical devices, sensors, audio preamps, industrial systems, and many other weak-signal applications.
Features:
- High Gain: Amplifies weak DC signals up to 1000× their original level.
- Dual-Stage Amplification: Two adjustable stages with individual potentiometers for precise gain control.
- Low Noise: Ensures clean signal amplification with minimal distortion.
- Voltage Output: Output = Input × Gain (first stage × second stage).
- Versatile: Works well in audio, medical, sensing, and industrial applications.
- Compact & Efficient: Small footprint with low power consumption; ideal for embedded systems.
Specifications:
| Parameter | Value |
|---|---|
| Power Supply | 3.5 – 24 V DC |
| Maximum Gain | Up to 1000× |
| Output Current | 15–20 mA (non-linear) |
| Amplifier Type | LM358 Dual Operational Amplifier |
| Dimensions | 45.3 × 16.2 mm |
| Gain Adjustment | 2 Potentiometers (1 per amplification stage) |
Applications:
- Medical Equipment: ECG, EEG, blood pressure monitors
- Sensor Amplification: Temperature, light, and motion detection systems
- Audio Equipment: Microphones, guitar preamps, signal boosters
- Industrial Automation: Signal conditioning for PLCs and SCADA systems
Installation & Usage Notes:
- The two on-board potentiometers adjust gain—turn counterclockwise to increase gain.
- Connect the signal input to the IN terminal and retrieve the amplified signal from the OUT terminal.
- Ensure power supply is within recommended range (3.5V–24V).
