A current source supplies a fixed current with high (ideally infinite) parallel internal impedance. Current source analysis (Kirchhoff’s current law, etc.) is useful for some circuits but actual ...

A Constant Current Sink/Source (CCS) pretty much does what it says on the tin – it provides a constant source of DC current through (or for) a device. You can construct a CCS out of lots of different ...

Linear Technology’s LT3092 is a 0.5- to 200-mA, twoterminal, low-temperature-coefficient, constant-current- source IC. Conceptually, it’s simple, but there has never been an IC ...

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 ...

At first glance, [RobBest]’s constant current source looks old school. The box is somewhat old-fashioned, featuring switches and binding posts. Most importantly, there’s a large analog meter ...

The A6278 from Allegro Microsystems is an 8-channel constant-current latched LED driver incorporating an open LED detection capability. It is a BiCMOS device which includes an 8-bit CMOS shift ...
