NOTES:
9. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
10. In the test circuit, there is no external capacitor applied to pin 7. However, when the device is plugged into a test socket, there is usually a very
small but finite stray capacitance present, on the order of 5pF.
11. The Intersil ICL7660S and ICL7660A can operate without an external diode over the full temperature and voltage range. This device will function
in existing designs that incorporate an external diode with no degradation in overall circuit performance.
12. All significant improvements over the industry standard ICL7660 are highlighted.
13. Derate linearly above 50°C by 5.5mW/°C.
