Notes
1. In the application, the reference current will be generated by means of a resistor. The given current can be realized
2. I
3. The voltage on TLN can be clamped with respect to GND (positive and negative) with one or two diodes. The clamp
4. In the TZA1020A, pin MIRN is clamped with respect to GND (positive) by means of one diode.

by a resistor of 1.3844 k . As these are not available, the actual reference current will be slightly different. This
means that all derived signal currents will be scaled in the same way
