Function
Supply Interface. Provides access to supply pins VNEG, COMM, and VPOS.
Monitor Interface. By adding 0 Ω resistors to R8, R9, R10, and R18, the VREF,
VSUM, VOUT, and VLOG pin voltages can be monitored using a high
impedance probe.
Buffer Amplifier/Output Interface. The logarithmic slope of the ADL5306 can
be altered using the buffer’s gain-setting resistors, R2 and R3. R4, R6, R11, R14,
C2, C7, C9, and C10 are provided for a variety of filtering applications.
Intercept Adjustment. The voltage dropped across resistor R1 determines the
intercept reference current, nominally set to 10 µA using a 200 kΩ 1% resistor.
Supply Decoupling
Filtering VSUM
Input Compensation. Provides essential HF compensation at the input pins,
INPT and IREF.
Input Interface. The test board is configured to accept a current through the
SMA connector labeled INPT. An SC style packaged photodiode can be used in
place of the INPT SMA for optical interfacing. By removing R1 and adding a 0 Ω
short for R5, a second current can be applied to the IREF input (also SMA) for
evaluating the ADL5306 in log-ratio applications.
