The ICL7660 / TL7660 is a popular CMOS charge pump voltage converter designed to invert a DC input voltage using just a few external capacitors. It can easily convert a +5V supply into a −5V output, making it ideal for circuits that require dual supply rails but only have a single positive supply available.
With high conversion efficiency (up to 99.9% typical in open-circuit conditions) and a wide operating range from 1.5V to 10V, this IC is well-suited for battery-powered and low-power applications. It is widely used in op-amp biasing, signal conditioning, data converters, and other analog/mixed-signal designs.
