IC LM358 OpAmp
Product information:
The LM358 has 2 separate high-gain OpAmps. With this you can make many circuits. You can, among other things, make a voltage from a digital PWM signal. For example, to control dimmable TL's or LED bars.
Voltages:
3V - 32V (with single power supply)
1.5V - +/-16V (with dual power supply)
