Current Mirrors
-
Analog Devices current mirrors are precision, high dynamic range, wide variable supply parts used for optical power monitoring, voltage biasing with current monitoring, and voltage-to-current conversion. Our current mirrors can monitor current down to as little as 3 nA and as much as 3 mA, with a linearity of 1% or better. The current dynamic range is 120 dB or 6 decades of current range, while the overcurrent protection feature in our devices forces the input pin to ground to avoid part damage. Over temperature (–40°C to +85°C) and process, the dynamic range only suffers 10 dB at the lower end of the range.

Multi-Channel, Programmable Current Source
CS-48-100
-
The Model CS-48-100 is a multi-channel, programmable current source. Developed for both semiconductor and digital superconductor electronics, it is computer-controlled and features 48 low noise current source outputs. Each source output has the capability to both set and read back currents and can be set to a zero current high Z mute state. Each of the 48 sources are optically coupled for control and are sourced from their own secondary winding for complete galvanic isolation. The device consumes a maximum of only 80 W and handles a maximum load current of 4.8 A total over all outputs. Operating over a range of 0-100 mA on each channel, the device features accuracy of +/-25 ?A. The mute state can be set thru a rear panel interlock or from the front panel button for maximum circuit protection. The unit can be mounted in a standard-sized rack.
