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).
