Function
Supply and ground connections.
Input Interface: The evaluation board is configured to accept an input current at the
SMA connector labeled INPUT. Filtering of this current can be done using L1 and C4.
Input Compensation. Provides essential HF compensation at the INPT pin.
INPT Bias Voltage. The dc voltage applied to VSET determines the voltage at INPT,
V
Opening SW1 allows for VSET to be driven externally via the SMA connector.
Output/Mirror Current Interface: The output current at the SMA connector labeled IOUT is
equal to the value at INPT. R5 allows a resistor to be installed for applications where a
scaled voltage referenced to IPD is desirable instead of a current.
Current Limiting. An external resistor to VPOS sets the current limit at INPT from
1 mA to 16 mA. I
