PIN I/O DESCRIPTION
NAME RRF NO. ZXL NO.
IREF 20 J1 I Pin for setting the maximum constant-current value. Connecting an external resistor between IREF and GND sets the maximum current for each constant-current output channel. When this pin is connected directly to GND, all outputs are forced off. The external resistor must be placed close to the device.
