I want do dim some hundert LEDs with analog dimming (current control, not PWM). There are various LED drivers that are able to analog dim. Two examples: A6211 and AL8860. But: can I control about 20 of them in parallel with only one direct analog signal (no op-amps or additional circuits)?
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) No, PWM is really no option. (Request by the client).
