This DC Voltage Amplifier gives you the ability to amplify the voltage of a signal with ease. When digital signals from your IC circuits are too low, you can use this amplifier to boost up the voltage! Ideal for transducer amplifiers, dc gain blocks, and all op-amp circuits. This amplifier module is based on the LM358 operational amplifier which is a high-gain, frequency compensated operational amplifier designed to operate from a single power supply over a wide range of voltages. It is used in conventional operational amplifier circuits that need to be operated from a single power rail.
