LM358 100 Times Gain Signal Amplifier Module R38

Description

The LM358 100 Times Gain Signal Amplifier Module is a ready-to-use module designed to amplify small analog signals with a gain of up to 100 times. It is based on the LM358 operational amplifier, which is a low-power, dual op-amp IC suitable for single-supply operation. Here’s a breakdown of the module’s features and details:

Features:

1. High Gain: Amplifies input signals by 100 times (adjustable with onboard potentiometer).
2. Low Power Consumption: Operates with low power requirements.
3. Wide Operating Voltage: Typically works within a voltage range of 3V to 12V DC.
4. Easy Integration: Equipped with input/output pins and a potentiometer for adjusting gain.
5. Versatile Applications: Can amplify signals from various sensors (e.g., thermocouples, microphones, and photodiodes).

Specifications:

• Chip: LM358
• Power Supply Voltage: 3V–12V
• Gain Adjustment: Potentiometer
• Input Signal: Analog signal (e.g., sensor outputs)
• Output Signal: Amplified analog signal
• PCB Size: Typically small (varies by module manufacturer)

Pin Description:

1. VCC: Power supply (3–12V).
2. GND: Ground.
3. IN: Analog signal input.
4. OUT: Amplified signal output.

Applications:

• Amplifying low-voltage signals from sensors.
• Audio signal amplification.
• Analog data preprocessing for ADC modules.
• Biomedical signal processing (e.g., ECG, EMG signals).
