Current sources are widely used in industrial control systems to transport analog process signals over long distances, but they are less widely used than voltage sources. This post loosely reviews the ...

The ever innovative and prolific Mr. Woodward has offered “PWM-programmed LM317 constant current source,” an intriguing programmable constant current source which elicited a lively conversation in its ...

Voltage references are available with fixed and adjustable reference voltage outputs. Adjustable output is set by a resistor divider connected to a reference pin. These references are either shunt ...
