FUNCTION
No Connection. Not internally connected.
1.238V Reference Voltage Output. Bypass REFVOUT to GND with a 0 to 1μF capacitor (optional).
Ground
Negative Power Supply. Bypass V
EE
to GND with a 0.1μF capacitor.
Logarithmic Amplifier Voltage Output 1. The output scale factor of LOGV1 is -0.25V/decade.
6
OSADJ
Offset Adjust Input. Apply a voltage at OSADJ to adjust the LOGV2 output offset voltage
(see the
Output Offset
section).
7
SCALE
Scale Factor Input. Adjust the output scale factor for LOGV2 using a resistive divider (see the
Scale
Factor
section).
8
LOGV2
Logarithmic Amplifier Voltage Output 2. Adjust the output scale factor for LOGV2 using a resistive
divider between SCALE, GND, and LOGV2 (see the
Scale Factor
section).
10
V
CC
Positive Power Supply.
Bypass V
CC
to GND with a 0.1μF capacitor.
Current Reference Adjust Input. A resistor (R
SET
), from REFISET to GND, adjusts the current at
REFIOUT (see the
Adjusting the Logarithmic Intercept
section).

CMVOUT
REFIOUT
0V Common-Mode Voltage Reference Output
Current Reference Output. The internal current reference output is available at REFIOUT.
14
REFIIN
Current Reference Input. Apply an external reference current at REFIIN. I
REFIIN
is the reference
current used by the logarithmic amplifier when generating LOGV1.
15
LOGIIN
Current Input to Logarithmic Amplifier. LOGIIN is typically connected to a photodiode anode or other
external current source.
16
CMVIN
Common-Mode Voltage Input. V
CMVIN
is the common-mode voltage for the input and reference
amplifiers (see the
Common Mode
section
)
