Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Power supply negative terminal (ground). |
| 2 | SCL | input | I2C clock input, supports up to 400 kHz and needs a pull-up resistor to the supply. |
| 3 | SDA | bidirectional | I2C data pin; the datasheet lists it as an input, but the chip pulls it low to acknowledge writes, and it needs a pull-up resistor to the supply. |
| 4 | OUT0 | output | Constant-current output channel 0, 3 to 40 mA, with output voltage above 0.7V needed for constant current. |
| 5 | OUT1 | output | Constant-current output channel 1, 3 to 40 mA, with output voltage above 0.7V needed for constant current. |
| 6 | OUT2 | output | Constant-current output channel 2, 3 to 40 mA, with output voltage above 0.7V needed for constant current. |
| 7 | OUT3 | output | Constant-current output channel 3, 3 to 40 mA, with output voltage above 0.7V needed for constant current. |
| 8 | OUT4 | output | Constant-current output channel 4, 3 to 40 mA, with output voltage above 0.7V needed for constant current. |

| 11 | OUT7 | output | Constant-current output channel 7, 3 to 40 mA, with output voltage above 0.7V needed for constant current. |
| 12 | OUT8 | output | Constant-current output channel 8, 3 to 40 mA, with output voltage above 0.7V needed for constant current. |
| 13 | OUT9 | output | Constant-current output channel 9, 3 to 40 mA, with output voltage above 0.7V needed for constant current. |
| 14 | OUT10 | output | Constant-current output channel 10, 3 to 40 mA, with output voltage above 0.7V needed for constant current. |
| 15 | OUT11 | output | Constant-current output channel 11, 3 to 40 mA, with output voltage above 0.7V needed for constant current. |
| 16 | OUT12 | output | Constant-current output channel 12, 3 to 40 mA, with output voltage above 0.7V needed for constant current. |
| 17 | OUT13 | output | Constant-current output channel 13, 3 to 40 mA, with output voltage above 0.7V needed for constant current. |
| 18 | OUT14 | output | Constant-current output channel 14, 3 to 40 mA, with output voltage above 0.7V needed for constant current. |
| 19 | OUT15 | output | Constant-current output channel 15, 3 to 40 mA, with output voltage above 0.7V needed for constant current. |

| 21 | OUT17 | output | Constant-current output channel 17, 3 to 40 mA, with output voltage above 0.7V needed for constant current. |
| 22 | REXT | input | Constant-current reference feedback pin; a resistor to ground sets the output current, with IOUT = (1.24V / Rext) x 12.5 (1240 Ω gives 12.5 mA). |
| 23 | ADDR | input | I2C chip address select: VDD = 4EH, GND = 46H, SCL = 4AH, SDA = 4CH (write only). |
| 24 | VDD | power_in | Power supply positive terminal, absolute maximum 0 to 5.5V. |
