Two process control signaling schemes were to be supported — the 0 to 10 VDC analog signal, and the venerable 4-20 mA current loop.

A Simple Over-Voltage Protection Circuit for LED Drivers This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V ...

The simple addition of a transistor and resistor to the open-circuit drive overcomes this dilemma by limiting current through the drive transistor. Transistor Q2 provides the open-collector drive ...

A simple circuit uses one control device to control bass and treble simultaneously, with a symmetric response that is flat at the center of the adjustment range.
