... Overvoltage up to 14V During prototyping, a common mistake is to power a device without checking the voltage output of one’s bench supply first. To ensure the ADXL322 chip on a DE-ACCM2G won’t get damaged by this, a zener diode in parallel with the ADXL322’s power pins clamps the voltage supplied to ...

Current source



A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
