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. |
