Constant Current Source Op Amp at Stephanie Dampier blog

Constant Current Source Op Amp. Current sink with voltage references. Precision current sink can be created with the combination of a transistor, amplifier, and voltage reference. A 1a or 300v current sink/source is easy with a transistor or darlington, and does not require a special $300. On reaching equilibrium, a constant. One variation of this technique is, instead to change the very source voltage, to add additional voltage in series to the constant source voltage thus compensating for the impact of. Using ref200 and one external op amp: And the voltage feedback to the control op amp increases until a state of equilibrium is reached. The current sink is shown in figure 2. For physics 240 we will use the tl3472. Current source or sink with compliance to power supply rail and current out >100µa you can build a programmable current source of virtually any value using two.
