tlc5940 - sharing a resistor when daisy-chaining

Other Parts Discussed in Thread: TLC5940

hello, I'm daisy-chaining 10 tlc5940 drivers.

I've calculated the required iref value to be 2.2k ohm.

right now I'm using 10 resistors. each driver has its own resistor.

I was wondering: is it possible (and advisable?) to use just a single resistor to control the IREF of all tlc5940 drivers in my circuit, or does every driver require its own IREF resistor, even though the values are the same across all chips.

thank you.
