An SCR topology transmogrifies into BJT two-wire precision current source with a self-resetting fault-current limiter.
The 4-20 mA transmitters used in industrial current-control loops can be implemented as powered current sources, remote non-powered current sinks, or with several other I/O combinations. A useful ...
When used in precision current mirror or current multiplier applications, the n-channel ALD1121E (dual) and ALD1123E (quad) precision MOSFET arrays can provide a current source from 100 nA to 3 mA and ...
