ICL7660CSA

TDSEMIC · Charge Pumps · SOP-8

ICL7660CSA from TDSEMIC, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BOOST input Oscillator frequency boost control; connect to V+ to increase internal oscillator frequency ×6; leave open (NC) when using an external oscillator signal at OSC.
2 CAP+ passive Positive terminal connection for the external charge-pump flying capacitor.
3 GND power_in Ground reference; the negative terminal of the reservoir capacitor connects here in most applications.
4 CAP- passive Negative terminal connection for the external charge-pump flying capacitor.
5 VOUT power_out Inverted (negative) voltage output; the positive terminal of the reservoir capacitor connects here in most applications.
6 LV input Low-voltage operation select; connect to GND when supply voltage is below 3.5 V to maintain proper operation.
7 OSC input Oscillator frequency control input; connect an external capacitor to GND at this pin to reduce the internal oscillator frequency below its default.
8 V+ power_in Positive supply voltage input, 1.5 V to 10 V; also serves as the chip's internal reference connection point.
