# ADM660ARZ-REEL

**Analog Devices** · DC-DC Converters · SOIC-8

ADM660ARZ-REEL from Analog Devices, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | FC | input | Frequency control input: open gives 25 kHz charge-pump frequency (10 µF capacitors), connected to V+ gives 120 kHz (2.2 µF capacitors). |
| 2 | CAP+ | passive | Positive charge-pump capacitor terminal for the external capacitor C1. |
| 3 | GND | power_in | Power supply ground in inverter configuration (positive input supply in doubler configuration). |
| 4 | CAP- | passive | Negative charge-pump capacitor terminal for the external capacitor C1. |
| 5 | OUT | power_out | Negative voltage output in inverter configuration (ground in doubler configuration). |
| 6 | LV | input | Low-voltage operation input: connect to GND when input voltage is below 3.5 V, above 3.5 V it may be connected to GND or left open; connect to OUT in doubler mode. |
| 7 | OSC | input | Oscillator control input with internal 15 pF capacitor; an external capacitor slows the oscillator or an external clock can overdrive it (charge-pump frequency is half the oscillator frequency); leave unconnected in doubler mode. |
| 8 | V+ | power_in | Positive power supply input (+1.5 V to +7 V) in inverter configuration; doubled positive output in doubler configuration. |
