Hello,

Trying to improve this circuit.

24V Supply from Battery, Display to react to Analog signal 0-10VDC

LED seems to dimm at higher voltages say 7V DC in graph mode.

Any suggestions?
Thank you in advance

Running with a 24 power supply when the absolute maximum power supply voltage is 25 volts might decrease reliability.

You don't need all those resistors in series with the LEDs because the chip has programmable output current.

Can't comment further because I am not familliar with the chiip.
