Ground
No Connection. Not internally connected.
LED1 Cathode Connection. LD1 is the open-drain output of an internal current
regulator for controlling the current through LED1. It is able to sink up to 25mA.
If not used, connect LD1 to GND.
LED2 Cathode Connection. LD2 is the open-drain output of an internal current
regulator for controlling the current through LED2. It is able to sink up to 25mA.
If not used, connect LD2 to GND.
LED3 Cathode Connection. LD3 is the open-drain output of an internal current
regulator for controlling the current through LED3. It is able to sink up to 25mA.
If not used, connect LD5 to GND.
LED4 Cathode Connection. LD4 is the open-drain output of an internal current
regulator for controlling the current through LED4. It is able to sink up to 25mA.
If not used, connect LD4 to GND.

LED5 Cathode Connection. LD5 is the open-drain output of an internal current
regulator for controlling the current through LED5. It is able to sink up to 25mA.
If not used, connect LD5 to GND.
LED6 Cathode Connection. LD6 is the open-drain output of an internal current
regulator for controlling the current through LED6. It is able to sink up to 25mA.
If not used, connect LD6 to GND.
LED7 Cathode Connection. LD7 is the open-drain output of an internal current
regulator for controlling the current through LED7. It is able to sink up to 25mA.
If not used, connect LD7 to GND.
LED8 Cathode Connection. LD8 is the open-drain output of an internal current
regulator for controlling the current through LED8. It is able to sink up to 25mA.
If not used, connect LD8 to GND.
Maximum LED Current Set Input. SETI sets the maximum current through each
LED. Connect SETI to IN for a default maximum current of 18mA; connect SETI to
GND for the 0.5mA LED test mode. Connect a resistor from SETI to GND to adjust
the maximum current between 12mA to 25mA (see the
Setting the Maximum LED
Current
section).

REF
1.25V Reference Output. Bypass REF to GND with a minimum 0.22μF ceramic
capacitor.
Brightness Control Input (Multimode):
DPWM Mode: Leave unconnected for greater than 50kHz operation. Add a
capacitor from BITB to ground for lower frequency operation.
Analog Mode: Analog control signal input.
2- or 3-Bit Parallel Mode: Digital input. Least significant bit (LSB) for 2-bit mode.
