I want to dim some hundred LEDs with analog dimming (current control, not PWM.). There are various LED drivers that are able to analog dim. Two examples: A6211 and AL8860. Can I control about 20 of them in parallel with only one direct analog signal, no op-amps or additional circuits?

A6211:

AL8860:

Some additional information:

  1. It will be a copper-core PCB (only one layer.). That's why the circuit should be as simple as possible.
  2. PWM is really not an option. (Request by the client.)
