| Market Reality | The ICL7660 is the two-capacitor negative-rail generator of analog benches: an 8-pin charge pump that turns +5 into -5 (or doubles a rail) with no inductor, at about 10 milliamps and 98-percent efficiency - the part behind op-amp negative supplies, RS-232-era negative rails and a thousand small split-supply designs. Its family is the substitution surface: MAX1044, LTC1044 and MAX660 share the pin map, and the fine print lives on PIN ONE, which is No-Connect on the ICL7660, a BOOST (6x frequency) on the MAX1044 and a frequency-control input on the MAX660 - so every socket is pin-compatible and every board that actually drives pin one is part-specific. The rest of the discipline is the LV pin and the caps. | The ICL7660 is the two-capacitor negative-rail generator of analog benches: an 8-pin charge pump that turns +5 into -5 (or doubles a rail) with no inductor, at about 10 milliamps and 98-percent efficiency - the part behind op-amp negative supplies, RS-232-era negative rails and a thousand small split-supply designs.
