DESCRIPTION

NAME

RRF NO.

ZXL NO.

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.
