EVALUATION BOARD
An evaluation board is available for the ADL5306, the schematic
of which is shown in 29. It can be configured for a wide variety
of experiments. The buffer gain is factory-set to unity, providing
a slope of 200 mV/dec, and the intercept is set to 1 nA. Table 4
describes the various configuration options.

Component
Function
Default Conditions
P1
Supply Interface. Provides access to supply pins VNEG,
COMM, and VPOS.
P1 = Installed
P2, R8, R9, R10, R18
Monitor Interface. By adding 0 resistors to R8, R9, R10,
and R18, the VREF, VSUM, VOUT, and VLOG pin voltages
can be monitored using a high impedance probe.
P2 = Not Installed
R8 = R9 = R10 = Open (Size 0603)
R18 = Open (Size 0603)
R2, R3, R4, R6, R11, R14, C2, C7, C9, C10
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.
R2 = R6 = 0 (Size 0603)
R3 = R4 = Open (Size 0603)
R11 = R14 = 0 (Size 0603)
C2 = C7 = Open (Size 0603)
C9 = C10 = Open (Size 0603)
VLOG = VOUT = Installed
R1, R19
Intercept Adjustment. The voltage dropped across
resistor R1 determines the intercept reference current,
nominally set to 10
A using a 200 k 1% resistor.
R1 = 200 k (Size 0603)
R19 = 0 (Size 0603)
R12, R15, C3, C4, C5, C6
Supply Decoupling
C3 = C4 = 0.01
F (Size 0603)
C5 = C6 = 0.1
F (Size 0603)
R12 = R15 = 0 (Size 0603)
C11
Filtering VSUM
C11 = 1 nF (Size 0603)
R13, R16, C1, C8
Input Compensation. Provides essential HF compensation
at the input pins, INPT and IREF.
R13 = R16 = 1 k (Size 0603)
C1 = C8 = 1 nF (Size 0603)
IREF, INPT, PD, LK1, R5
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 short for R5, a second current can be applied
to the IREF input (also SMA) for evaluating the ADL5306 in
log-ratio applications.
IREF = INPT = Installed
PD = Not Installed
LK1 = Installed
R5 = Open (Size 0603)
J1
SC Style Photodiode
J1 = Open
