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.

Test Sets For Transformer Industries
Contemporary Test Sets For Transformer Industries are developed to recognize the potentially disastrous current transformer errors. They prevent the primary current from overpowering insulation and short circuits. They are used for developing a testing and maintenance plan for addressing the errors before any failure to save money and time. With these powerful test sets, they are sure to perform saturation testing to test the knee point of a signal by comparing primary and secondary windings.
