5 pcs LM358 Weak Signal Amplifier Module Two-Stage Operational Amplifier Module DC 3.5-24V 1000 Times gain Single Power Signal Collector

About this item

• Module features: LM358 is the two-stage core operation amplifier that can amplify weak DC signals such as DC voltage signals and DC pulse signals.
• Amplify weaker signals:It can amplify signals that are millivolts or even weaker, and the two potentiometers on the board rotate counterclockwise to increase multiples.
• Maximum Gain Multiplier: 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.
• Voltage and current:Power supply voltage: 3.5-24V DC;Current output:maximum 15-20MA
• Item Condition: The module is 100% made of original electronic components, and the product is a product, you can buy it with confidence
